high polished mica glass machinable ceramic rod tube parts customized factory
Mica Glass Ceramic:
Microcrystalline glass ceramics, also known as machinable ceramics, are mica glass-ceramics with synthetic mica as the main crystalline phase, and are ceramic materials that can be machined. Microcrystalline glass ceramics have excellent processing properties, vacuum properties, electrical insulation properties, and high temperature and chemical resistance. Glass-ceramics have high mechanical strength of glass-ceramics, machinable glass-ceramics and bioactive glass-ceramics.Machinable ceramics refer to ceramic materials that can be drilled, turned, milled, etc. with tools and instruments for metal processing.
Mica Glass properties:Good insulativity, high temperature(800°), good machinable property, can be made of rod and plate in short time.
