Based on the step cooling curve method, also known as the Cooling curve method, it is used to measure the change relationship between the melt temperature and time during the gradual uniform cooling of the melt from high temperature. When the melt starts to cool from the liquid and gradually precipitates solid phases, the temperature time graph of the melt shows horizontal segments and turning points. The step cooling curve can observe the corresponding temperature when the solid phase precipitates, which is the initial crystal temperature.

1. The temperature thermocouple directly contacts the sample to be tested, making the test results more accurate;

2. It can be seen as an equilibrium measurement, and the results are closer to the true value.
