white fused alumina

/

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.

Characteristic

1.High hardness

2.High purity

3.Good self-sharpening

4.Strong grinding ability

5.Acid-alkali corrosion resistance

6.High temperature resistance and

7.Good thermal stability

Production process

White fused alumina was made from the high quality by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha---Al2O3.

Application

1.Spraying and grinding.

2.High-end products, crafts or hardware products surface beautification processing.

3.Precision casting, silicon crystal cutting, advanced refractories and ceramic additives.

4.Bonded abrasives and coated abrasives.

5.Processing harder and stronger tensile strength materials such as quenching steel, alloy steel, high speed steel and high carbon steel.

6.Ultra-precision Grinding and Polishing in Crystal and Electronics Industry, Precise Surface Treatment of Metal and Optical Products

7.Contact media, insulators and precision casting sand.
