Product Description


Macor mica machinable Ceramics:


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 with high mechanical strength, glass-ceramics, machinable glass-ceramics and bioactive glass-ceramics


Macor ceramics have excellent processing properties, vacuum properties, electrical insulation properties, and high temperature and chemical resistance. Glass-ceramics with high mechanical strength of glass-ceramics, machinable glass-ceramics and bioactive glass-ceramics



1. High intensity and light weight
Glass-ceramics are harder than natural stone and are not easily damaged. The thickness of the material can be matched with the construction method, which is in line with the light and sturdy mainstream of modern buildings.



2, rich and varied colors
Glass-ceramics are made by the accumulation method. There is no natural stone texture (which breaks from here). The accumulation method is a method that can produce rich color tones, with a white color as the basic color and a rich color system, and white The three colors of rice and gray are most often used.



3. Excellent weather resistance and durability
The acid-resistant and alkali-resistant glass-ceramics are superior to granite and marble, and are inherently inorganic materials. Even when exposed to wind and rain and polluted air, they will not cause deterioration, fading, and inferior strength.



4. 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.



5,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. 


Properties


High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.

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.
