High-purity fused silica with over 99.9% SiO2. Particle size can be adjusted from a minimum of 0.3µm. It is also compatible with spherical and sharp particle size distributions.
(This is a product handled by Japan Freeman Co., Ltd. For inquiries, please call 045-473-3580.) We carefully select high-purity raw materials and carry out high-temperature melting using specialized equipment. After that, the manufacturing process includes steps such as foreign matter removal. ーーーHM Seriesーーー We have a proven track record of supplying to precision casting companies in Europe and the United States, where strict particle size management is required. Leveraging that experience, we are expanding sales to semiconductor and electronics manufacturers as well. ーーーNV Seriesーーー We can accommodate a minimum particle size of 0.3µm while achieving sharp particle size distribution and adjustable bimodal particle size distribution. In addition to general shapes, we offer spherical and needle-like forms. We have a proven track record of supplying to a wide range of industries, including cosmetics, semiconductors, and paints. We achieve low prices through our unique import routes. We are also happy to provide quotes and samples, so please feel free to contact us. ーーーProduct Characteristicsーーー - Can be manufactured from ultra-fine particles - Bimodal and sharp particle size distributions are achievable - Chemically stable - High purity (high SiO2, low Al2O3, Fe2O3, etc.) - High wear resistance and hardness - A variety of lineups including spherical and submicron fine particles are available.
