Alumina ceramic crucibles are used in scientific experiments and materials such as molten metals. Made of 95 alumina ceramics, it has high temperature and corrosion resistance and lasts longer than other materials.
Under normal circumstances, first put the object to be analyzed into the crucible or crucible, and then heat it. The heating speed and the temperature drop depend on the characteristics of the equipment and products, whether it is fast or slow, because the thermal expansion of the raw materials can cause cracks that are easy to produce, or make them grow quickly. The best way is to heat them slowly, which can extend their service life.
