Product features of alpha-phase 99.9% 3N Al2O3 powder
Stable phase, high hardness, materials with high dimensional stability, it is widely used in a variety of plastics, rubber, ceramics, refractory products for reinforcement toughening, in particular, significantly to improve the ceramic density, finish, thermal fatigue resistance, fracture toughness, creep resistance and wear resistance. As the α-phase Al2O3 is a high performance material of far infrared emission, it is widely used to produce artificial ruby, sapphire, yttrium aluminum garnet and also used in the field of fiber fabric products and high pressure sodium lamp as far-infrared emission and thermal insulation materials. In addition, α-phase nano-Al2O3 with high resistivity and good insulation property, it is widely used as the main components for YAG laser crystal and integrated circuit substrates.
