Engineered Powders Division

We use specialist “powder control technology” to provide a range of high performance metal powders. One of our key strengths is our extensive range of products for various different purposes, including cerium oxide abrasives used for polishing glass in products such as LCD panels and hard disks, extrapure tantalum oxide used in SAW filter, and metal powders (copper, silver) for use in electronic equipment and battery materials. We also develop, manufacture and sell powders in line with our customers’ needs, in terms of particle size and shape.
