Glass ceramics can be machined with conventional metal working machinery. It is not necessary to sinter after machining, because strength, hardness and zero-porosity remain intact during machining. Machinable glass ceramic have the following power feature.Features.
a) Is machinable with ordinary metal working tools.
b) Allows fast turnaround,no post firing required.
c) Holds tight tolerances, up to .0005"
d) Withstands high temperature, up to 800
e) Is clean, no outgasing and zero porosityApplication.
MGC: Machinable glass ceramic have the following applications:
a) Electrical or thermal insulator
b) Structural components
c) Semi-conductor processing
d) Electrical and opto-electronic equipment
e) Many other uses.Properties of production:
