MGC Machinable Glass Ceramic has a continuous use temperature of 800°C. Its coefficient of thermal expansion readily matches most metals and sealing glasses. It is nonwetting, exhibits zero porosity, and unlike ductile materials, won’t deform. It is an excellent insulator at high voltages, various frequencies and high temperatures. And when properly baked out, it won’t outgas in vacuum environments.
MGC Machining tolerances are surprisingly tight, up to .0005″. It can be machined to a surface finish of less than 20?in. and polished to a smoothness of 0.5µ. Configurations are limited only by available equipment and the experience of the machinist.
Sealing, Joining and Metalizing
MGC can also be joined or sealed – both to itself and to other materials. – in a number of ways: metalized parts can be soldered together and brazing has proven an effective method of joining the material to various metals; epoxy produces a strong joint, and sealing glass creates a vacuum tight seal. Even a straightforward mechanical joint is possible. It can be thick film metalized using metal inks, or thin film metalized by sputtering.
