Product List

High Purity Alumina

Characteristics	High purity alumina is made by oxidizing, micronizing, and firing high purity smelted aluminum pellets in a unique process. Micronized into a highly pure, micron-level powder, this alumina offers high performance for electrical insulation and high strength.
Applications	Raw material for ceramics, raw material for fluorescent materials, raw material for glass, catalysts, etc.
Typical Quality Data	Aluminum hydroxide (RH-30, 40), highly active alumina (RK-30, 40), active alumina (RG-30, 40), α-alumina (RA-30, 40), fine powder α-alumina (SA-1, R-2)

High Purity Alumina (For Sapphire Monocrystals)

Characteristics	Formed into spherical granules, this high purity alumina is ideal for manufacturing sapphire and other monocrystals. The near-spherical granules offer high purity and fluidity to enable efficient filling of crucibles for crystal growth.
Applications	Sapphire monocrystals
Typical Quality Data	FGL Series (low density granules), FGH Series (high density granules)
