What is white aluminum oxide as wear-resistant filler used for?
White aluminum oxide is widely used as wear-resistant filler for the following products due to its high hardness (Mohs hardness above 9.0), excellent wear resistance, chemical stability and thermal stability:
Coatings (especially wear-resistant coatings, anti-corrosion coatings, floor coatings, powder coatings, UV coatings, etc.)
Adding white aluminum oxide micropowder can significantly improve the hardness, wear resistance, weather resistance, anti-slip and corrosion resistance of the coating, and extend the life of the coating. Suitable for heavy-loaded floors, industrial floors, ships, chemical equipment, etc.
Plastics and Rubber
White aluminum oxide is added as a filler to enhance the wear resistance, hardness and strength of plastic products (such as wear-resistant tool grinding discs, gears, guide rail parts) and rubber products.
Ceramics and Special Ceramics
White aluminum oxide is used as a filler or reinforcing agent to improve the hardness, strength, wear resistance and high temperature performance of ceramic products. It is also used for precision polishing materials.
Refractory and Casting Materials
Use the high hardness, high temperature resistance and chemical stability of white aluminum oxide to enhance the wear resistance and erosion resistance of refractory bricks, castables, etc. It is also used as a wear-resistant component of casting sand.
Mortar and Concrete
Adding white aluminum oxide to mortar can greatly improve its wear resistance, compressive strength, corrosion resistance (acid and alkali resistance) and durability, and is suitable for heavy loads or corrosive environments such as roads, bridges, and chemical facility foundations.
Grinding and Polishing Materials
White aluminum oxide can be directly used as a sandblasting abrasive to remove metal oxide layers and rust; it can also be made into polishing powder for precision polishing of optical glass, semiconductor chips, ceramics, etc.
Chemical Industry (such as Catalyst Carrier)
White aluminum oxide is used as a catalyst carrier material, taking advantage of its chemical inertness, high specific surface area and wear resistance.
Core advantages support its application range:
High hardness and wear resistance: Far superior to most metal and non-metal materials.
Chemical stability: Resistant to acid and alkali corrosion.
Thermal stability: Good high temperature resistance.
Wide range of particle sizes: From coarse particles (such as 8 mesh/2360-2800μm) to ultrafine powders (such as 10000 mesh median D50: 1.0um), they are available to meet different application requirements.
White aluminum oxide particle size distribution characteristics: concentrated particle size, narrow span
