What’s Is Machinable Glass Ceramic?

Machinable Glass Ceramic is a mica glass ceramic material with a unique combination of properties. It is easily machinable using conventional metalworking tools, with no post-firing required. A versatile ceramic material with technical strength and insulation properties exceeding high-performance plastics, it is also stable in high temperatures (continuous at 800° Celsius, up to a peak of 1,000° Celsius) with 0.0069% porosity. The ceramic material also acts as an electrical insulator that is radiation resistant and has low thermal conductivity.
