Product Description:
Brown fused alumina, also known as brown aluminum oxide, is a type of synthetic abrasive material that is made by fusing bauxite with other materials in an electric arc furnace. Brown Fused Alumina uses high-quality bauxite, iron filings, and anthracite as raw materials, and is smelted at a high temperature in an electric arc furnace to exceed 2000℃.
Key Properties:
- high hardness, toughness, chemical stability, and low heat conductivity
- high purity, good crystal fluidity, low linear expansion coefficient, corrosion resistance, high-temperature resistance, and high strength
- Hardness: 9 mohs, Melting point: approx. 2050°C
- Al2O3: 95,20%, TiO2: 2,45%, Fe2O3: 0,15%
Applications:
- abrasive material, production of refractory materials and for surface preparation
- grinding, polishing, sandblasting, precision casting, etc., for refractory materials
- refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding
