With Machinable Glass Ceramic (MGC), fabrication is fast - because it can be machined into complicated shapes and precision parts with ordinary metal working tools, quickly and inexpensively, and it requires no post firing after machining. That means no frustrating delays, no expensive hardware, no post fabrication shrinkage, and no costly diamond tools to meet specifications.


Property of Machinable Glass Ceramic

*High use temperature (800°C continuous; 1000°C peak).

*Low thermal conductivity and is a useful high temperature insulator.

*Excellent electrical insulator and is used extensively throughout the semiconductor and electronic industries.

*MGC has no porosity and when properly baked, will not outgas. It is widely used in ultra high vacuum applications. 

*Strong and rigid. MGC is unlike high  temperature plastics, it will not creep or deform.

*Radiation resistant and plays a key role in nuclear applications and nuclear-related research and development.

*MGC can be thick or thin film metallized, brazed, epoxy and frit bonded.
