[0002] Alumina, also known as aluminum oxide, is an inorganic compound composed of aluminum and oxygen elements. It is a common ceramic material with the characteristics of high melting point, high hardness and good wear resistance. Alumina is widely used in various fields. Among them, the most common application is as the main component of ceramics. Alumina ceramics have excellent physical and chemical properties, so they have important application value in the manufacture of electronic devices, disk transmission devices, engine parts and high-temperature kilns. The strength of alumina needs to be tested. Alumina has good wear resistance, high temperature resistance and corrosion resistance, so it is widely used in various industries. Different application fields have different strength requirements for alumina, so strength testing is required to ensure that it meets the corresponding standards and needs.
