MACHINABLE GLASS CERAMICS Introductions Is MACHINABLE with ordinary metal working tools; Allows FAST TURNAROUND, no post firing require; Holds TIGHT TOLERANCES, up to 0.012(0.0005”); Withstands HIGH TEMPERATURE, up to 1000°C(no load); Is CLEAN, no outgasing and zero porosity; Machining Machining tolerances are surprisingly tight, up to 0.012(0.0005”). it can be machined to a surface finish of less than 0.5(20uin).-AA. Configurations are limited only by available equipment and the experience of the machinist. Sealing, Joining and Metalizing Machinable Glass Ceramic(MGC) can also be joined or sealed – both to itself and to other material – 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 straight-forward mechanical joint is possible. It can be thick film metalized using metal inks, or thin film metalized by sputtering.

Ultra-High Vacuum Environments Machinable Glass Ceramic is used as an insulator or coil support and for vacuum feed-throughs. In these applications, the conductive materials are supported by the MGC part and a compatible sealing glass is used to produce a vacuum-tight, hermetic seal. Constant Vacuum Applications MGC parts are found in spacers, headers and windows for microwave tube devices and as sample holders in field ion microscopes. Aerospace Industry Over 200 distinctly shaped MGC parts can be found on America’s reusable Space Shuttle Orbitec. Retaining ring of MGC are used at all hinge...
