Home » Our Businesses » Grinding and Abrasive Materials Business
Our powder business with the trademark Nisso Rundum has been known to our customers for more than half a century, and its main application is grinding and polishing. We have wide selection of products from coarse particles to ultrafine powder made from silicon carbide powder and alumina powder as a comprehensive manufacture of abrasive powder.
Our silicon carbide products and alumina products are used for grinding wheels and coated abrasives, refractory bricks, fine ceramics, and raw materials for semiconductor manufacturing component in diversified sectors. Their applications have recently been expanded into new fields, such as base materials for ceramic filters, raw materials for composite materials with metals (MMC: Metal Matrix Composites), and raw materials for SiC power devices.
