Alumina, or aluminium oxide, is one of the most versatile industrial powders. It is hard, thermally stable and chemically resistant, which is why it appears in so many processes.
Ceramics and refractories
Alumina is a core raw material for technical ceramics and refractory linings, where it withstands high temperatures and wear.
Abrasives and polishing
Fine alumina powders deliver consistent surface finishing in polishing compounds and abrasive products. Narrow particle-size control gives a repeatable finish.
Coatings and catalysts
Alumina is used as thermal-spray feedstock for wear-resistant coatings and as a support material for catalysts.
What to specify
The key parameters are alumina content, median particle size, soda level and phase. Share these with your supplier and ask for a Certificate of Analysis with each lot.
