Alumina is a very chemically ionized substance with a high melting point, hardness and high chemical stability, especially it can maintain high hardness and strength at high temperatures, and this AlO is widely used. Used in metallurgy, machinery, chemical industry, electronics, medicine, aviation and national defense. Due to the ultra-micronization of alumina powder, its surface electronic structure and crystal structure have changed, resulting in surface effects that macroscopic objects do not have. , Small size effect, quantum effect and macroscopic quantum tunneling effect.
The influence of too much sodium oxide in alumina powder on ceramics
High temperature alumina powder is made of industrial aluminum hydroxide and bauxite, molecular sieve and grinding balls as raw materials. It is calcined in a tunnel kiln for a long time at high temperature. It has a high melting point, excellent mechanical strength, hardness, high resistivity and Thermal conductivity. It
