We provide crystal products with a rutile-type structure that is a single crystal of TiO2.
- TiO2 has three types of crystal structures, and Shinkosha provides crystals with the rare rutile structure found globally. - Due to its high refractive index, birefringence, and wide transmission characteristics, it is used as an optical core component. - In the field of photocatalysts, it is also used for fundamental research that takes advantage of the characteristics of single crystals. - Because of its good crystallinity and the ability to perform step & terrace treatment on the surface, it is widely used as a substrate for thin film deposition.

Company information
Our company is a manufacturer of oxide single crystals. In particular, we specialize in the following products: 1. Sapphire (α-Al2O3) 2. SrTiO3 3. Rutile (single crystal of TiO2). Although we are a crystal manufacturer, we also perform a full range of processing, including cutting, grinding, and polishing. Having handled crystals for over 70 years since our founding, we possess extensive knowledge and experience, especially regarding sapphire. Recently, we have also been mass-producing sapphire crystals larger than 300mm, allowing us to accommodate large-shaped products and mass production. We are a small company with about 170 employees, but if there is anything we can assist you with, please feel free to contact us.
