Types of White Corundum Powders Available
Coarse Powder
Coarse white corundum powder is produced by milling larger white corundum grains into a coarse salt-like texture.
Specialty Powder for Refractory Materials
Some sectors, notably the refractory and ceramic industries, need white corundum powder particles to have a particular size and purity.
Premium Super Fine Abrasive Powder
The ultra-fine variety of white corundum powder is produced by carefully monitoring the milling process to get an incredibly uniform and fine particle size.
Micro-Powder
White corundum powder is available as micro powder. It is processed by crushing white corundum crystals into fine particles, often less than 10 micrometers in size.
Applications
Electronics
In the electrical and electronic sectors, white corundum powder is insulated and separated materials.
Precision Polishing
Industrial precision polishing makes a great application of white corundum powder.
Agriculture
In agriculture, white corundum powder improves soil health and is chosen as a soil amendment.
Industrial Coatings
Refinements in coatings are another application of white corundum powder. It acts as an anti-slip agent in floor coatings.
