White fused alumina fine powder from 0 to a 45μm particle size in segment sand is also called -325 mesh fine powder, which can be directly used as refractory materials or further processed into a micro powder. White fused alumina (WFA), also named white aluminium oxide, white corundum. It’s made from high-quality industrial alumina powder, which is melted in an electric arc furnace at over 2,000 degrees. It is then cooled, crushed and shaped, magnetically separated to remove iron, and sieved into various particle sizes.
Introduce white fused alumina fine powder -325:
White fused alumina is from the reduced fusion of high purity alumina powder containing aluminium oxide(Al2O3). White fused alumina has a very high refractory temperature and acid resistance. Alkali corrosion resistance is stable in chemical content and has high true gravity/density, low porosity rate, and thermal shock resistance. It’s an excellent corundum aluminium oxide refractory material. White fused alumina is an essential high-end material for producing shaped and unshaped refractory products.

Applications of white fused alumina fine powder -325:
Porosity is defined as the gas proportion (cavity volume) of a particle’s total volume. It can be determined using different measurement techniques, such as gas adsorption and mercury porosimetry. With the same grain size and shape, a lower bulk density corresponds to a higher porosity of the grains.
Generally, it will take 30 to 60 days after receiving your advance payment. The specific delivery time depends .on the items and the quantity of your order.
Yes. According to NIOSH, Brown Aluminum Oxide could be a viable substitute for consumers looking for safer alternative materials to high crystalline silica content abrasive products.
Yes.FREE SAMPLES 5kg can be provided for your evalution.
The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best stored at temperature levels of 60 to 80 degrees Farenheit and a
When processing minerals in a furnace, materials can either be melted or sintered. When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process
