Superfine alumina is an important raw material for functional ceramics. Superfine alumina powder xz-L20, particle size 100 nm, colour white, 99% of solid content. It can be added to Various water-based resins, within oil-based resins, solvents and rubbers at an addition level of 3%-5%, which can significantly improve the hardness of the material up to 6-8H or even higher.

Grain Q-A1203, with its low chemical surface and high temperature resistance, is not a dry activated alumina, and has no catalytic activity. It has strong heat resistance, good formability, stable crystalline phase, high hardness and good dimensional stability, and can be widely used in the reinforcement and toughening of various plastics, rubber, ceramics, refractory materials and other products, especially to improve the denseness, finish, hot and cold fatigue, fracture toughness, creep resistance of ceramics and the wear resistance of polymer materials.
