1,About product
High purity alumina has become one of the important special functional materials because of its excellent physical and chemical properties. Because of the true density, Mohs hardness, wear resistance, corrosion resistance, heat insulation, easy sintering, and good mechanical properties, etc., showing that the conventional materials with optical, electrical, magnetic, thermal and mechanical properties, is one of the tip materials production led sapphire substrate material, lithium battery protection membrane, integrated circuits on ceramic substrates, green lighting with an important basis for trichromatic fluorescent powder, automotive sensors, tape additive, catalyst, coating carrier, semiconductor and liquid crystal display, transparent high pressure sodium lamp, precision instrument and aero optical devices materials and in the production of new materials in the 21st century the largest and highest value, use the most widely.
