White Corundum Aluminium Oxide Powder Fused Alumina for Sandblasting Refractory
product description
White Fused Alumina / White Aluminum Oxide/White Fused Aluminum Oxide/Whit Corundum/WA /WFA
White Fused Alumina is a high purity, synthetic mineral,manufactured by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000C followed by a slow solidification process. Strict control over quality of raw materials and fusion parameters ensure products of high purity and high whiteness,high hardness, toughness is a bit low, excellent self sharpening, grinding force, low calorific value, high efficiency,acid and alkali resistance, good thermal stability.
Al2O3 white fused alumina compound refractory material is an optimal refractory material to make refractory products:
Section sand 0-1mm,1-3mm,2-3mm,3-5mm,5-8mm:
- Shaped refractory products such as refractory bricks
- Unshaped refractories aggregates in furnace building
Fine powder -100#,-200#,-320#:
- Unshaped refractories castables for ladles
- Refractory paint and coatings
- Foundry sand in precision casting
