Aluminum Oxide Powder (Alpha) Products Features:

A-phase ultrafine Al2O3: phase stability, high hardness, materials with high dimensional stability, is widely used in a variety of plastic, rubber, ceramic, refractory products for hardening of reinforcement, specifically to significantly improve the finished product density Resistance to thermal fatigue, fracture resistance, sliding resistance and wear resistance. Since the ultrafine α phase Al2O3 is a high-performance far-infrared emission material, it is widely used in fiber weaving lamp and high-pressure sodium up infrared emission and thermal insulation materials. Furthermore, high-resistivity Al2O3 phase A and good insulating properties are widely used as main components for YGA crystal lasers and integrated circuit substrates.
