DESCRIPTION
White Fused Alumina is made from high-purity alumina powder fused in an electric arc furnace at above 2050℃. It is a high strength, high hardness material with pure white color and and sharp edges. It has high refractoriness, superior electrical insulating properties, outstanding chemical stability, high corrosion & thermal shock resistance, which makes it a desirable material choice for abrasives & refractories application.
