APPLICATIONS
Glass and ceramics are both excellent electrical insulators. The dielectric properties of ceramics are used in capacitance and microwave applications.
Examples include:
Machined MACOR components provide very high dielectric strength in high voltage applications
Machined quartz insulators are used in a similar way
Glass to metal seals provide electrical insulation while allowing hermetic packages to be made
High accuracy discs in glass and ceramics are used as capacitance standards
Metal-ceramic assemblies are used in X-ray tubes
These interlocking beads are used to insulate wires, particularly at high temperature
