B. Electrical Properties
Microcrystalline glass ceramics is an excellent high-temperature electrical insulating material that can be used in many electrical equipments. It has high electrical insulation strength.
C. corrosion resistant
because it is completely composed of inorganic materials, so there is no aging and no deformation, very stable to various organic solvents and good acid and alkali corrosion resistance.

Application industry:
Machinery, electronic, limitary, aerospace etc.
Specific application: Machined equipment high temperature insulated parts, electronic equipment high temperature insulated parts.
Macor ceramics are particularly suitable for automotive, military, aerospace, precision instruments, medical equipment, electric vacuum devices, electron beam exposure machines, textile machinery, sensors, mass spectrometers and energy spectrometers. For some thin-walled coil bobbins, precision instrumented insulation brackets, and complex-shaped devices with high precision requirements, glass-ceramics are more suitable, and they can be processed into any shape.
