The characteristics of nano-sized alumina features
nano-sized alumina the characteristic features of this product with a white fluffy powder, according to the crystal shape is mainly divided into HTAl - 01,α- nmAl2O3； Particle size & le; 80 nm, specific surface area < 10 m2 / g; HTAl - 02年,γ- nm Al2O3； 3030 aluminum particle size & le; 20 nm, specific surface area & le; 200 m2 / g, uniform particle size distribution, high purity. 03 ~ 09 said models using different forms of surface treatment. The characteristics of nano alumina due to the small particle size, can be used to make artificial gemstones, analytical reagent and nano-sized catalyst and carrier, used in luminescent material can greatly improve the luminous intensity, for ceramics, rubber toughening and is several times higher than normal alumina, especially improve the density of ceramic, degree of finish, cold and hot fatigue, etc. 3030 aluminum nanometer alumina is mainly used for main parts and integration YGA laser crystal substrate 3030 aluminum extrusions, and used in coating to improve the wear resistance.
