We have a lineup of polycrystalline alumina powder, calcined alumina powder and their slurry products refined by Saint-Gobain's unique manufacturing method. Other than alumina, we also handle zirconia, boron carbide and others. These products are widely used in semiconductors, hard and brittle material wafers, hard disks, automobile repair materials, etc. where precision polishing is particularly required.

We also develop and manufacture our own coolants, lubricants and cleaners, which are essential to cutting, grinding and polishing, and provide package solutions with abrasive grains.
