Description

technical field

[0001] The invention relates to a standard sample used for temperature calibration of a thermogravimetric analyzer and a preparation method thereof. Specifically, it relates to a standard sample product for preparing a calibration temperature of a thermogravimetric analyzer by using a sol-gel method, and belongs to the field of standard substances . Background technique

[0002] Thermogravimetric analyzer is the most commonly used thermal analysis instrument. It is quantitative and can be widely used in physics, chemistry, materials and other fields. It can be said that as long as the weight of a substance changes when it is heated, it can be studied by thermogravimetry. its changing process. When using a thermogravimetric analysis (TG) instrument for testing, temperature calibration is very important. At present, there are three methods for calibrating the temperature: one is to use a standard material that can indicate the temperature and have a reproducib...
