White fused alumina fine powder 200-0

White fused alumina fine powder 200-0 is made of high-quality industrial alumina powder cooled and smelted at a more than 2000 degrees temperature in an electric arc. White fused alumina is crushed and shaped by a jaw crusher and a ball mill; The fine powder is the product passing through the 200 mesh screen in the refractory sand production line. Its compact texture, high hardness, suitable for the manufacture of ceramics, grinding of high tensile metal and grinding, polishing, sandblasting, precision casting, etc. It can be used as a high-quality powder for shaped refractory and amorphous refractory.

Introduce white fused alumina fine powder 200-0:

White fused alumina Using high-quality alumina powder as raw material by refining and crystallizing in an electric arc furnace at high temperature. It has white colour, is slightly harder and has lower toughness compared with brown fused alumina. Its microhardness is 2200-2300kg/mm² with high purity, good acid and caustic corrosion resistance, high-temperature resistance and good thermal stability.

White Fused Alumina(FAQ)

What is silicon carbide?

Silicon carbide is a chemical compound of silicon and carbon and belongs to the group of carbides. The chemical formula is SiC.Silicon carbide is at the same time the hardest and lightest ceramic material and is also highly resistant against acids and alkaline solutions.

How do i know what abrasive is best for my application?

An abrasive’s shape, hardness, and particle size really determine the effectiveness of a MicroBlasting application. Each application is unique, and abrasive selection depends on the composition of the targeted part and the application’s desired result. See our Abrasive Media Selection Guide to choose the most appropriate abrasive for your application.

How is silicon carbide obtained?

Silicon carbide (SiC) is produced from coke and quartz sand applying the Acheson process in an electric resistance furnace. When petrol coke and quartz sand are grouped around a graphite electrode and heated to a temperature of 2,000°C, black and slightly higher-quality green SiC are obtained. Green SiC has a
