Alumina ceramic rings have high mechanical stability and excellent acid resistance, and can be corroded by various inorganic acids, organic acids and organic solvents (except HF acid) in various occasions, and have a wide range of applications. 
Alumina ceramic macrorings have high hardness, excellent wear resistance, corrosion resistance and high temperature resistance, good self-lubrication, and are not easy to scale. Alumina ceramics are the most common advanced precision ceramic materials, and they are also relatively traditional materials. As an excellent ceramic material, high-purity alumina ceramics have been widely used in many industries. The material has excellent properties in terms of electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion. Alumina is widely used in the aerospace field, and has many properties such as high strength, high temperature resistance, oxidation resistance, and corrosion resistance. Alumina can be prepared to be high temperature and heat resistant, and is used for insulating tiles and flexible insulating materials on space shuttles. In the field of high-temperature industrial furnaces, alumina is mainly used as insulation and refractory materials because of its low density, good heat insulation, and small heat capacity.
