Product Description

Product Description

Macor Machinable Glass Ceramic Plate

Machinable glass ceramic is a highly electrical insulating, heat insulating, vacuum tight composite material of glass and ceramics.
It is machinable with common tungsten carbide or high speed steel cutting tools by turning, milling, drilling and sawing.

Property of Machinable Glass Ceramics

1. MGC can be machined with ordinary metal working tools and there is not need for post firing - meaning fast turnaround
 
2. It has a continuous use temperature of 800 C and the the max. Is up to 1000 C.
 
3. MGC has low thermal conductivity, it is a exellent temperature insulator.
 
4. MGC has no porosity and will not outgas when properly baked. It is widely used in ultra high vacuum applications.
 
5. MGC has high electric insulativity and it is used extensively throughout the semiconductor and electronic industries.
 
6. MGC has radiation resistant and plays a key role in nuclear applications and nuclear-related research and development.
 
7. MGC is unlike high temperature plastics, it will not creep or deform.
 
8. MGC can be thick or thin film metallized, brazed, epoxy and frit bonded.

Application

·Electrical insulation – high-voltage components, spark plug insulators, heater bases.
 
·Thermal protection – furnace fixtures, brazing jigs, heat shields.
 
·Mechanical parts – wear-resistant bushings, bearings, seal rings, pump pistons.
 
·Chemical resistance – acid/alkali pump liners, valve seats, laboratory tools.
 
·Precision fixtures – semiconductor wafer handlers, vacuum chucks, measuring instrument supports.
 
·High-frequency electronics – antenna radomes, microwave windows, capacitor cores.
