Embodiment 1

[0024]Embodiment 1 The structure of the diamond counter-anvil press of the present invention will be described with reference to the accompanying drawings.

[0025] The structure of the diamond anvil press of the present invention is as figure 1 , 2 , 3, 4 shown. figure 1 , 2 , 3, 4, 1 is alloy steel, 2 is beryllium copper, 3 is mica sheet, 4 is shaking table, 5 is diamond anvil, 6 is gasket, 7 is spiral heating wire, 8 is thermocouple, 9 is Pneumatic quick connector, 10 is the circulating water chamber, 11 is the upper mold of the press, 12 is the inner wall of the upper mold cylinder, 13 is the lower mold of the press, 14 is the cylindrical piston, 15 is the cylindrical piston holder, and the cylindrical piston 14 and cylindrical piston holder 15 form an integral body to form press lower die 13, and 16 is the lower die piston outer wall.

[0026] The diamond anvil press of the present invention has the same structure as the prior art: a press consisting of a press upper ...

Embodiment 2

[0028] Embodiment 2 The assembly process of the internal cooling diamond anvil press of the present invention

[0029] First clean the two diamond anvils 5, then fix the diamond anvils 5 on the shaker 4 with a high-temperature repair agent, put the shaker 4 into the press, and place a layer between the shaker 4 and the press The mica sheet 3 with a hole in the center is balanced and centered so that the anvil surfaces of the upper and lower diamond anvils 5 are completely coincident. The sample to be tested is packaged between two diamond anvils 5 and sealed with a pre-pressed gasket 6 on which a spiral heating wire 7 has been pre-arranged. The heating wire 7 and the thermocouple 8 are led out through the small hole of the lower die 13 of the press for heating and temperature measurement. Utilize the pneumatic quick plug 9 to connect the water pipe and the circulating water cavity 10 of the upper and lower parts of the press, and connect the water chiller and the water pump i...

Abstract

The invention discloses an inner-condensing diamond anvil cell pressing machine and belongs to the technical field of an in-situ physical quantity measurement device at high temperature and high pressure. The device comprises a pressing machine made of high-strength alloy steel (1) and beryllium copper (2), one pair of diamond anvil cells (5), a rocking bed (4) among the pressing machine and the diamond anvil cells (5), a mica sheet (3) between the pressing machine and the rocking bed (4), a spacer (6) between the two diamond anvil cells (5), spiral heater strips (7) wound on the spacer (6), a thermoelectric coupler (8), pneumatic fast joints (9) connected with a circulating water cavity (10) and a water pipe in the pressing machine, an external water-cooling machine and a water pump. The pressing machine is heated by the spiral heater strips and cooled by circulating water so that the high-temperature environment can be provided for the sample, and the pressing machine can be retained at a normal temperature status without pressure loss; a testing device for in-site measurement of multiple physical quantities at a high-temperature and high-pressure extreme condition and a testing method for the in-site measurement are established.

Description

technical field [0001] The invention belongs to the technical field of in-situ measuring devices for physical quantities under high temperature and high pressure conditions, and in particular relates to a device for measuring various physical parameters of samples under extreme conditions such as high temperature and high pressure in a diamond counter-anvil. Background technique [0002] Diamond Anvil Cell (DAC for short) is currently the only scientific device capable of generating a static pressure of one million atmospheres, and is the most important scientific instrument in the field of high-pressure science and technology research. Using DAC, people can observe changes in the structure and physical properties of substances in ultra-high pressure environments, especially in the laboratory simulation of the pressure and temperature environment of the deep earth. The laboratory simulates the pressure and temperature environment in the deep part of the earth to study the st...
