Applications:
Aluminum oxide nanoparticles show high hardness and high dimensional stability. It is used to improve toughness, wear resistance, thermal fatigue resistance, and ceramic density for rubber, plastics, and ceramics. It is used in high strength aluminum oxide ceramic, high purity crucibles, furnace tubes, and cutting tools. It is added to metal products, semiconductors, tapes, polishing materials, and glass products. Aluminum oxide nanoparticles have excellent properties for far infrared emission. It is used in fiber fabric products and high pressure sodium lamp as far-infrared emission and thermal insulation materials. In addition it is used in the field of catalysis as catalyst or catalyst carrier.
