Product Description

High purity alumina powder uses high-purity alumina as the main material and is prepared by the hydrolysis method. It has the performance characteristics of high purity, stable particle size, and spherical powder shape. It can be used for the preparation of transparent and translucent alumina ceramic tubes, ceramic substrates, etc. Because the AO ceramic body has a high melting point, it is difficult to form, and its lattice constant is close to that of AO, so it can form a solid solution with AO. At the same time, they are variable-valence oxides. Due to the variable-valence effect, AO porcelain produces defects, activates the crystal lattice, and promotes the formation of porcelain. The transparent ceramic tube for high-pressure sodium lamps prepared with this product has a full line transmittance of 97%, and a linear transmittance of less than 0.1.
