White Corundum Fused Alumina Natural Corundum Powder in Low Price Low-Sodium Electronic Industry

Product Description

 

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

White corundum grain size sand ,high hardness and dense particles. Single-particle roundness is good.Uniform distribution of particle size, single-particle shape consistent,Chemical stability and, high-temperature stability is very good.

Grain size sand:

• Abrasive tools made of it are suitable for grinding high-speed, high carbon steel,etc.     
• It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials,etc.

White Fused Alumina Micropowder

White Fused Alumina Fines: 

white, strong cutting force. Good chemical stability and good insulation.

It is suitable for wet or dry sandblasting, suitable for ultra-fine grinding and polishing of crystal and electronic industries, and making advanced refractory materials, etc.
