White Fused Alumina (97%min Al2O3) in High Purity for Industrial Furnace

White fused alumina



Description:
White fused alumina(WFA), a kind of high-grade refractories, is made from the imported quality alumina by melting above 2000 c in the electric arc furnace and cooling. It is white with the main crystal phase a-AL2O3. The white alumina produced in the titling electric arc furnace has the advantage of high bulk density and low porosity, thus the volume stability and thermal shock resistance can be improved.

Performance and advantages
1. Not affecting the color of the processing cases
2. Sandblasting in the non-iron process
3. Powder level ideal for wet blasting and light lapping
4. High speed process and quality
5. Containing a very low amount of iron oxide, suitable for non-ferrous blasting operations
6. After acid washing steps


Usage:
1. Available research in a variety of blasting and light lapping operations
2. The process of beautifying glass or acrylic
3. The process of blasting TV screens
4. The cutting of silicon wafer
5. The process of cleaning and blasting tooth model
6. Precision sand casting
7. High refractory and other ceramic additives
