TOHO Titanium High-Purity Titanium Dioxide
Pred Materials is pleased to market Toho Titanium's advanced TiO2 powders. These are produced by gas-phase reactions between refined TiCl4 and O2 under specially controlled conditions at high temperatures. With such high purity, these powders are used mainly in the electric and electronic industries as the material for electro-ceramic parts, such as PTC (Positive Temperature Coefficient) thermistors and MLCC (Multi-Layer Ceramic Capacitors). Our TiO2 has recently found applications in optical glass lenses, replacing lead-containing compounds. Production capacity is 180 metric tons per month.
