White Fused Alumina (WFA or WA) is an important raw material for advanced refractories and abrasives, a widely used raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding, and hundreds of other applications. As it is a very pure, low iron alumina, specific refractory applications include high tech refractory castables, isostatic pressed refractories, and pre-cast refractory shapes. The benefits of White Fused Alumina in these applications are high alumina content, low impurities, and stability at high temperatures.
Introduction white corundum: The raw material of white corundum is AL2O3. The production process is that after the alumina is smelted into a block in a high temperature furnace by a high temperature, it is broken into small pieces by a jaw crusher, and then crushed by a ball mill for secondary crushing, magnetically removed and then sieved into various models. The micropowder needs to be pickled and removed. White corundum has high purity, good self-sharpness, low calorific value, strong grinding ability, and good corrosion resistance. It has higher hardness than brown corundum, but it has no toughness of brown corundum. White corundum characteristics: 1. High alumina content and high hardness 2. self-sharpening, acid and alkali corrosion resistance 3. high temperature resistance, stable thermal performance, 4. Strong grinding ability, low heat generation and high efficiency. Chemical Composition AL2O3 99.2-99.7; Fe2O3 0.03-0.1; Na2O 0.23-0.32; SiO2 0.03 Main Physical Properties Mohs hardness:9 Bulk density:1.75-1.95g/cm3 Real density:3.95 Melting point:2250 Application 1. Surface processing of auto parts manufacturing plants, stone factories, glass factories, glasses factories, electronics factories, etc. 2. Atomizing aesthetic processing of glass or acrylic art; 3. Fine grinding and polishing of the workpiece 4. Matting or matte treatment of gold, precious metal products, mobile phones, flat panels, etc. 5. Application of stress removal for aircraft turbine blades, aircraft wings, aircraft landing gear support beams, etc.
Introduction white corundum: White fused alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.It is suitable for surface beautification of glass and metal, and can also be used as raw material for sandblasting and rust removal.
