Forsterite Ceramics

MgO-Al2O3-SiO2 ceramics are composed of 2MgO-SiO2 (also called Mg2SiO4) forsterite crystals.
Our forsterite is free of magnesia crystals (periclase).
NAC manufactures forsterite using carefully selected materials and under dense and meticulous quality control.

Feature

フォルステライト

Forsterite is widely used as an electrically insulating material because of its light yellow appearance, smooth surface, and high strength. 
It is also useful as a high-frequency insulating material because of its low dielectric constant of 6.5 and low dielectric loss tangent (Tanδ).
It is used in insulating parts for vacuum tubes and base materials for metal film resistors, where adhesion to metal is essential because of its significant coefficient of thermal expansion (8 to 12 x 10-6/°C).
