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