Introduction of White Aluminium Oxide:
White fused alumina is made from high quality alumina by being melted above 2000°C in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance.






Typical properties of White Aluminium Oxide:
High Hardness
High Compression Strength
Abrasion/ Wear-Resistance
Abrasives
Chemical Inertness
High Degree of Refractoriness
Superior Electrical Insulating Properties
Dielectric Properties
High Melting Point
