Applications:
Aluminum oxide nanoparticles exhibit high hardness and dimensional stability. They are used to enhance toughness, wear resistance, thermal fatigue resistance, and ceramic density in rubber, plastics, and ceramics. Applications include high-strength aluminum oxide ceramics, high-purity crucibles, furnace tubes, and cutting tools. They are also added to metal products, semiconductors, tapes, polishing materials, and glass products. Aluminum oxide nanoparticles provide excellent far-infrared emission properties and are used in fiber fabrics and high-pressure sodium lamps for far-infrared emission and thermal insulation. Additionally, they serve as catalysts or catalyst carriers in various catalytic processes.
