White Fused Alumina
Raw Material And Process Of Production:
White Fused Alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions at high temperature. The dense mineral is white in color, and has predominantly large crystals of Alpha 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.
KT Refractories distributes white fused alumina grains and powders, available in standard grit and powder sizes, and they can also be made to individual specifications. Contact KT Refractories for white fused alumina or other refractory

Product Performance
White fused alumina Occupying higher hardness and slightly lower toughness compared with Brown Fused Alumina, it is characterised by its high purity, better cutting,ability of self-sharpening, less heat emit during grinding, higher efficiency,acid and alkali resistance, and good thermal stability. Abrasive tools made of it are suitable for grinding high-speed, high carbon steel,etc.
Application:
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.
