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