Nanometer Aluminum Oxide (Al2O3)

Introduction of the Product

The product is a white loose powder, and is mainly divided into two types according to the different crystals: α and γ. Due to its small grain size, nano aluminum oxide can be used to make artificial jewel, analytical reagent, nano catalyst and carrier. It can greatly improve the luminous intensity, when used in the luminescent material. For the plasticization and reinforcement of ceramics and rubber, it is better than the ordinary aluminum oxide by several times, especially for the improvement of the compactness, finish and fatigue resistance of ceramics. Nano aluminum oxide is mainly used in the principal fittings of YGA laser crystal and the base plate of integrated circuit as well as in coating to improve its wear ability.
