The newly developed "angular nano-alumina" differs from conventional alumina in that its particle size is uniform and the particle size distribution is very sharp. The primary particle size can be controlled arbitrarily between 100 and 700 nm, and the crystal system can also be controlled depending on the application. It is used as an abrasive for device polishing slurries, fillers for resins and paints, and as a raw material for ceramics. 【Features】 ■ Uniform shape ■ Uniform particle size ■ Size control is possible ■ Crystal system control is possible *For more details, please refer to the PDF document or feel free to contact us.

"WA" is a representative precision processing micro-powder made from white alumina, used for a wide range of applications. It is produced by finely grinding and granulating fused alumina, and consists of high-purity alumina with an Al2O3 purity of 96.0% or higher, composed of α-type corundum crystals. It has a hardness second only to silicon carbide, maintains a sharp particle size distribution and stable particle shape, enabling advanced surface processing. 【Features】 ■ Exhibits excellent performance as a material for ultra-finish precision grinding wheels, ultra-finish abrasive cloth, and polishing tapes for ultra-precision surface finishing. ■ Suitable for precision lapping of metals without tensile strength, glass, quartz, semiconductor crystals, etc. ■ Chemically inert and resistant to high temperatures. ■ Outstanding stability in reaction with organic substances. ■ Widely used as a high-grade filler material (filling material) such as epoxy resin insulators. *For more details, please refer to the PDF document or feel free to contact us.

"PWA" is a high-quality alumina-based polishing material composed of plate-like crystals with an Al2O3 purity of 99.0% or higher. It has excellent heat resistance, is chemically inert, and is not affected by acids or alkalis.

PWA is a high-quality alumina powder composed of plate-like crystals with an Al2O3 purity of 99.0% or higher. Alumina is excellent in heat resistance and electrical insulation, and it is chemically inert, unaffected by acids or alkalis. It also has a hardness second only to silicon carbide. For this reason, it is expected to be used as a filler material (filling material, heat dissipation (thermal conductivity)) aimed at providing insulation and wear resistance. Our plate-like alumina has the following features: 1) Unique shape: high aspect ratio plate-like 2) Lineup: average particle size ranging from 3µm to 30µm 3) Sharp particle size distribution: our proprietary classification technology [Expected Applications] - Filler material: providing insulation and wear resistance - Providing low aggressiveness to the counterpart - Providing optical properties (such as light diffusion)

"WA" is a white alumina powder composed of α-type corundum crystals with an Al2O3 purity of 96.0% or higher. White fused alumina is chemically inert, heat-resistant, and possesses extremely high insulation properties, as well as hardness second only to silicon carbide. For this reason, it is also used as a filler material for enhancing insulation and wear resistance. Our white fused alumina offers a wide range of products with average particle sizes from approximately 0.3µm (#30000) to 60µm (#240). It is characterized by a sharp particle size distribution and stable particle shape, allowing us to meet our customers' specific needs. [Expected Effects] - Electrical insulation filler (improving insulation for low to high voltage components, etc.) - Wear-resistant filler (enhancing durability of resin components, etc.) - Raw material for friction materials (improving friction properties of brake pads, etc.)
