High Moisture Resistance White Fused Alumina Refractory 99% Al2O3 White Corundum Aluminium Oxide

Product descriptions from the supplier

Product Description
White Fused Alumina(WFA)
White Fused Alumina(WFA) uses first grade low sodium industrial alumina as raw material,which is melted at 2250℃ in a high-temperature electric arc furnace.then crushed into different grain size after magnetic separation.It has high purity of 99.2% alumina and high whiteness,so it is named as white fused alumina. White Fused Alumina(WFA) has the advantages of low sodium content,high purity,high temperature resistance,low porosity,large bulk density,good thermal stability,and good acid and alkali corrosion resistance. It is suitable for manufacturing ceramics, grinding tools, as well as grinding, polishing, sandblasting, precision casting, etc. It can also be used to manufacture advanced refractory materials.
