Macor Machinable Glass Ceramic Disc

In order to cater the varied demand of the customers, we are manufacturing and supplying an excellent quality spectrum of MACOR Machinable Glass Ceramic Disc in Xiamen, Fujian, China. Machinable glass ceramic has a continuous use temperature of 800A C and a peak temperature of 1000A C. Its coefficient of thermal expansion readily matches most metals and sealing glasses. It is non-wetting, exhibits zero porosity, and unlike ductile materials, wont deform. It is an excellent insulator at high voltages, various frequencies and high temperatures. And, when properly baked out, it wona t outgas in vacuum environments.

Applications
Ultra-high vacuum environments
Machinable Glass Ceramic is used as an insulator or coil support and for vacuum feed-troughs. In these applications the conductive materials are supported by the Machinable Glass Ceramic part and a compatible sealing glass is used to produce a vacuum-tight, hermetic seal.

Constant vacuum applications
Machinable Glass Ceramic parts are found in spacers, headers and windows for microwave tube devices and as sample holders in field ion microscopes.
