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 incorporated into metal products, semiconductors, tapes, polishing materials, and glass products. These nanoparticles provide excellent far-infrared emission properties, making them suitable for fiber fabric products and high-pressure sodium lamps for far-infrared emission and thermal insulation. Additionally, they are used in catalysis as catalysts or catalyst carriers.
