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