N-6805B Black color steatite
 |
This unique material is developed by Nishimura as parts of rear-projection TV or projector (e.g.prism). Since N-6805B is specially designed for glass attachment, it has the same thermal expansion property as BK-7 (One of the Grass material grades). The color is intended to prevent light reflection.

N-68 Steatite
 |
Steatite (MgO-SiO2) is a type of ceramic constituted by crystals of MgO and SiO2. The raw material is processed by talc, with the addition of a few kinds of auxiliaries. It made our steatites have better strength than other ceramics even in the same firing temperature. They are commonly used as electrical insulation parts.
