High-Purity Titanium Oxide (Titanium Dioxide)
High-purity titanium oxide powder with a purity level of 3N or higher
Our high-purity titanium oxide is produced by the vapor-phase oxidation method. In the method, titanium tetrachloride, a chloride of titanium, is vaporized and then oxidized with oxygen to produce titanium oxide. Our advantage is that we can produce high-purity titanium oxide at the 3N or 4N level by using high-purity titanium tetrachloride refined for titanium metal refining as a raw material.
Purposes of use
Our high-purity titanium oxide is processed into barium titanate at our customers’ sites and used in various electronic parts. Furthermore, our high-purity titanium oxide is used as additives for optical lenses, pharmaceutical products, foods, etc., given its high purity. Our high-purity titanium oxide production process is the only one that has obtained a pharmaceutical manufacturing license and a food additive manufacturing license among Japanese titanium oxide manufacturers.
