text: Cordierite is a crystalline material demonstrating relatively high refractoriness, having a melting point of about 1460°C., and, in a pure form, exhibits excellent electrical insulating properties and a relatively low coefficient of thermal expansion over the range up to 1000°C., viz., about 16 × 10-7 /°C.
