Current situation and development of thermal analysis technology and sample cup

In this paper, the basic principles of thermal analysis and the structure of thermal analysis device are briefly reviewed. The structure and properties of thermal analysis sample cup made of different materials and temperature sensor are summarized, and their advantages and disadvantages are indicated. Also, the thermocouple sample cup made of resin sand and thermocouple sample cup made of graphite are described in detail. Thermal analysis device is mainly composed of the sample cup and data acquisition and processing system, and the thermocouples are pre-embedded in the cup to monitor the temperature. The resin sand cup is widely used while it is disposable. Although the graphite sample cup and Cu sample cup can be reused, they can only be used in the thermal analysis of aluminum alloys.
