Al (alumina) Compound

Aluminum oxide (alumina) is a ceramic featuring high heat resistance, high thermal conductivity, high strength, a high degree of hardness, electric insulation, and high corrosion resistance.
We offer products that can also be used as materials of single crystals and as catalysts, including highly pure alumina from Iwatani Chemical Industry Co., Ltd.
In addition, we have been dealing in alumina to be used mainly as a raw material of refractory materials, such as white fused alumina and bauxite, which are used by a wide range of customers.

high purity alumina

高純度アルミナ
高純度アルミナ

High purity alumina is a product made by oxidizing, micronizing, and firing highly pure smelted aluminum pellets in a unique process.
Micronized into highly pure, micron-level powder, the alumina fulfills a high level of functions such as electric insulation and a high degree of strength.

■Applications
Raw material of ceramics, raw material of fluorescent materials, raw material of glass, catalyst, and others
■Products offered
Aluminum hydroxide (RH-30, 40)
Highly active alumina (RK-30, 40)
Active alumina (RG-30, 40)
α-alumina (RA-30, 40)

high purity alumina for sapphire single crystal

高純度アルミナ

This is a high purity alumina made into spherical granules, which are appropriate for manufacturing single crystals such as sapphire single crystals.
Made into near-spherical granules that feature high purity and fluidity, the alumina enable the highly efficient filling of crucibles for growing crystals.

■Application
Sapphire single crystal
■Products offered
FGL Series (low-density granules)
FGH Series (high-density granules)
