[0067] See also Figure 1-6 The present invention provides a technical solution based on any one of the first to ninth embodiments: a method for using an ultra-high temperature rapid heating hot plate, the specific steps of the method are as follows:

[0068] S1: Fix the B-type thermocouple heating platform 13 to the high temperature resistant base;

[0069] S2: placing the sample on the B-type thermocouple hot stage 13, and supplying corresponding gas based on the vacuum and atmosphere control component 15 to adjust the atmosphere in the hot stage furnace body 1;

[0070] S3: The temperature and heating curve required for the experiment are set by the external controller 19, and the B-type thermocouple heating table 13 is heated to the target temperature. The light temperature compensation window 14 is used to assist in increasing the heating temperature. The light temperature compensation window 14 uses the current electric heating lamp, which is the existing technology and will not be described in detail here;

[0071] S4: Observe the behavior of the sample in the hot stage furnace body 1 under high temperature environment.

[0072] S5: After the experiment is completed, turn off the power supply and take out the sample after it cools down to a safe range.

[0073] The hot stage of this solution can not only achieve extreme heating up to 1800℃, but also the heating rate can reach 900℃ / minute. And through the side observation window 4 of the hot stage furnace body 1, the contact angle test between the material and the platinum-rhodium alloy and other materials can be realized.

The size of the wire pressing groove 11 on the high temperature resistant base is precisely matched with the B-type thermocouple hot stage 13 to ensure its stable installation and excellent electrical and thermal conductivity.

[0075] The two ends of the B-type thermocouple hot stage 13 are connected to the external controller 19 through a platinum-rhodium wire and a copper wire respectively. The platinum-rhodium wire is used to transmit the temperature signal of the hot stage, and the copper wire is used to provide the heating current; the external controller 19 accurately adjusts the input current by real-time monitoring of the temperature signal of the thermocouple to achieve a temperature control accuracy higher than ±0.1°C.

The high-temperature resistant base of the hot stage can be made of alumina and zirconia to ensure the structural stability at a high temperature of 1800°C. The B-type thermocouple hot stage 13 is embedded in the wire pressing groove 11 of the high-temperature resistant base, and its welding end is pressed into a thin sheet for placing the sample and realizing the heating and temperature measurement functions. The sample is prepared into a small disc with a diameter of 2mm and a height of 2mm by a powder pressing method and then placed in the middle of the B-type thermocouple hot stage 13. The experimental environment is adjusted to an argon atmosphere by the vacuum and atmosphere control component 15.

[0077] During the experiment, the external controller 19 sets the heating rate to 600°C / min and the target temperature to 1650°C. Through the side observation window 4, the sample melting and contact angle changes are monitored in real time using a high-resolution camera. As the temperature rises, the sample begins to soften and gradually melts at 1400°C. When it is completely melted at 1650°C, its contact angle with the hot plate is stabilized at 54° ( Figure 7 The temperature control accuracy is ±0.1℃, ensuring the reliability of experimental conditions and data accuracy. The experimental results show that the system exhibits strong wettability in the molten state.
