Applications:
Aluminum oxide micron powder provides high hardness, excellent dimensional stability, and strong thermal and mechanical properties. It is used to enhance toughness, wear resistance, thermal fatigue resistance, and ceramic density in rubber, plastics, and ceramics.
Additional applications include:
-
High-strength alumina ceramics
-
High-purity crucibles and furnace tubes
-
Cutting tools
-
Additives for metals, semiconductors, tapes, polishing compounds, and glass
-
Far-infrared emission and thermal insulation materials (e.g., fiber fabrics, high-pressure sodium lamps)
-
Catalysts and catalyst carriers
