The reactor 10 has at least two transparent parts 101 and at least two cavities 11 (four cavities 11 are shown in the figure) arranged as partitions. When the hydration reaction is performed, the cavity 11 is in a closed state. The cavity 11 is used to accommodate at least two wafers 200, and the projection of a transparent part 101 is placed in a cavity 11. The reactor 10 has an open state to expose the cavity 11. For example, the reactor 10 may include a shell, a cover and a partition, the partition is placed in the space surrounded by the shell and the cover to form at least two cavities 11, and the partition may be vacuum glass. For example, the cover may be connected to the shell by hinge or screw connection, so that the reactor 10 can have an open state. The reaction component 40 includes a gas cylinder 41, a pressure gauge 42, a gas valve 43, a water inlet pipe assembly 44 and a microscope 45. Each gas cylinder 41 is connected to a cavity 11 through an air inlet pipe 48, so the number of reaction components 40 can be the same as the number of cavities 11 and the two can be set in a one-to-one correspondence. Exemplarily, the gas cylinders 41 of different reaction components 40 can deliver different types of reaction gases, so that the user can conduct a comparative experiment of multiple groups of gases in the same reaction device. Exemplarily, the gas cylinders 41 of different reaction components 40 can deliver the same gas, and wafers 200 with different crystal planes (exemplarily, the crystal plane roughness can be different) are placed in different cavities 11, so that a comparative experiment of different crystal plane parameters can be conducted at the same time. The pressure gauge 42 is used to detect the pressure value in the gas cylinder 41, so that the gas cylinder 41 can be controlled to deliver a certain amount of reaction gas into the cavity 11 according to the change of the pressure gauge 42. The gas valve 43 is arranged between the pressure gauge 42 and the reactor 10. The gas valve 43 and the pressure gauge 42 are both installed on the air inlet pipe 48, and the gas flow rate of the gas cylinder 41 can be adjusted by the gas valve 43.

Exemplarily, the water pipe assembly 44 can move forward and backward or rotate relative to the cavity 11, so that the position of the water pipe assembly 44 can be adjusted. The water inlet pipe assembly 44 is used to drip an aqueous solution between two adjacent wafers to form a hydrate. Each microscope 45 is arranged relative to a transparent portion 101 to photograph the evolution process of the hydrate, and the specific evolution process may include the process of synthesis and decomposition.

[0041] Specifically, a predetermined volume of aqueous solution can be first added between the two chips 200 in the cavity 11 through the water inlet pipe assembly 44 to form a liquid bridge between the two chips 200, and then a preset amount of reaction gas is transported into the cavity 11 through the gas cylinder 41, so that the reaction gas undergoes a hydration reaction in the liquid bridge to form a hydrate. The microscope 45 can take images of the reaction process in real time or intermittently, and the user can observe the synthesis of the hydrate reaction on the computer 20.

[0042] In the present application, the reactor 10 of the reaction device 100 is provided with at least two cavities 11 and at least two transparent parts 101. In addition, the reaction device 100 also includes at least two reaction components 40, so that the reaction device 100 can pass different types of gases into different cavities 11, or put wafers of different crystal plane types into different cavities 11, so that the reaction device 100 can perform multiple groups of comparative experiments, thereby improving the experimental efficiency. In addition, providing multiple cavities 11 in the same reactor 10 is also conducive to improving the integration of the device, thereby helping to reduce the integrated volume of the device.

[0043] In some embodiments, reference Figure 1 At least two cavities 11 are arranged flat in two rows, that is, at least two cavities 11 can be observed simultaneously from the top of the reactor 10. The flat arrangement helps to reduce the height difference between each cavity 11, thereby facilitating user operation.

[0044] In another embodiment, at least two cavities 11 may be arranged vertically.

[0045] In some embodiments, reference Figure 1 and Figure 2 , the microscope 45 is arranged relative to the top of the reactor 10, so as to facilitate the adjustment of the field of view of the microscope 45.

The crystal support assembly 46 includes two crystal supports 461 arranged relatively and spaced apart. The end surface of the crystal support 461 relative to the transparent portion 101 is recessed to form a first groove 4613. The first groove 4613 has an opening relative to the other crystal support 461 (not shown in the figure). The two side walls of the first groove 4613 adjacent to the opening are recessed to form a second groove 4614. The second groove 4614 is used to fix the wafer 200.

Exemplarily, the base 462 can be fixed by welding or bonding. The crystal support 461 includes a first part 4611 and a second part 4612 stacked in a stepped manner. The first part 4611 is connected to the base 462 by a connecting pin 463, and the second part 4612 is arranged relative to the transparent part 101. The first groove 4613 is at least provided in the second part 4612. In the application, the first groove 4613 is provided in the first part 4611 and the second part 4612, and the second groove 4614 is provided in the second part 4612. The base 462 and the crystal support 461 are connected by the connecting pin 463 to facilitate the removal and installation of the wafer, thereby preventing the wafer from being worn during the removal and installation process.

[0049] In some embodiments, the cavity 11 has a gas outlet 110, and the gas outlet 110 can be opened and closed. Specifically, the opening and closing of the gas outlet 110 can be achieved by plugging or disengaging a plug, or by a valve and a pipeline. For example, the pipeline is connected to the gas outlet 110, and the valve is installed on the pipeline, and the opening and closing of the gas outlet 110 are adjusted by the valve. The gas outlet 110 is provided to discharge the residual reaction gas in the cavity 11 after the hydration reaction and / or the gas generated during the decomposition of the hydrate, and the hydrate decomposition process when the pressure is reduced can also be observed.

[0050] In some embodiments, in combination Figure 1 and Figure 2, the water inlet pipe assembly 44 includes a dropper 441, a water pipe 442 and a water valve 443. The dropper 441 is used to drip an aqueous solution between two adjacent wafers to form a hydrate. At least part of the dropper 441 is arranged in the cavity 11, and the water pipe 442 is connected between the water reservoir 30 and the dropper 441. In the present application, at least two water inlet pipe assemblies 44 are connected to the same water reservoir 30. In another embodiment, at least two water inlet pipe assemblies 44 can be connected to different water reservoirs 30. The water valve 443 is installed on the water pipe 442 to control the water output of the water reservoir 30. The computer 20 is also electrically connected to the water valve 443. The water valve 443 is opened and closed according to the instructions of the computer 20, and the preset volume of aqueous solution can be dripped in by remote control, thereby facilitating the improvement of the operation convenience and operation accuracy of the reaction device 100. In addition, the size of the drip nozzle of the dropper 441 is usually smaller than the size of other parts, which is also convenient for controlling the dripping position.

[0051] In some embodiments, the water inlet pipe assembly 44 may further include a rotating member 444 , and the rotating member 444 is connected between the drip tube 441 and the water pipe 442 .

[0052] In some embodiments, reference Figure 1 , the reaction device 100 also includes a cooling system 50.

The reactor 10 is also provided with a cooling chamber 12, and the cooling chamber 12 is separated from the cavity 11. The cooling chamber 12 is connected to the cooling system 50 through a cooling pipe 51. The cooling chamber 12 is also arranged around the circumference of at least two cavities 11. The cooling system 50 added to the reaction device 100 can adjust the temperature of the reaction system to the target temperature, so that the hydration reaction at different temperatures can be studied. In specific operations, the temperature of the system can be adjusted to the target temperature by the cooling system 50, and then the reaction gas can be transported into the cavity 11.

[0053] In some embodiments, the reaction component 40 also includes a sensor 47, which is arranged in the cavity 11. The sensor 47 is used to detect the pressure and / or temperature in the cavity 11. In the present application, the sensor 47 is used to detect the pressure and temperature simultaneously. Exemplarily, a temperature-pressure integrated sensor can be used to realize the simultaneous pressure and temperature, or a pressure sensor can be used to detect the pressure, and a temperature sensor can be used to detect the temperature. The sensor 47 is electrically connected to the computer 20 to transmit the detected data to the computer 20. The coordination of the sensor 47 and the pressure gauge 42 can verify the accuracy of the intake volume, and the coordination of the sensor 47 and the cooling system 50 can verify the accuracy of the temperature control. In addition, the sensor 47 detects the pressure and / or temperature in the cavity 11, which can also ensure the safety of the device. It is understandable that the sensor 47 can be turned on before the hydration reaction.
