Applications:
Aluminum Oxide Micron powder exhibits high hardness and excellent dimensional stability. It is used to enhance toughness, wear resistance, thermal fatigue resistance, and ceramic density in rubber, plastics, and ceramics. Aluminum Oxide Micron powder is applied in high-strength aluminum oxide ceramics, high-purity crucibles, furnace tubes, and cutting tools. It is also incorporated into metal products, semiconductors, tapes, polishing materials, and glass products. Aluminum Oxide Micron powder features excellent far-infrared emission properties. It is not radioactive and does not contain heavy metals. When stored in a dry environment, it remains free of toxic and carcinogenic substances. Additionally, Aluminum Oxide Micron powder is used in fiber fabric products and high-pressure sodium lamps as a far-infrared emission and thermal insulation material. It is also utilized in catalysis as either a catalyst or a catalyst carrier.
