Macor machinable ceramic parts

Macor machinable ceramics is a high-performance material developed by Corning in the United States, and the main component is mica glass ceramics. It has unique physical and chemical properties, combining the advantages of high strength, high hardness, high temperature resistance, corrosion resistance of ceramics, and can be turned, milled, drilled, and ground with ordinary tools like metals. This material can achieve extremely high accuracy during processing, with dimensional tolerances controlled within ± 0.0005 inches, and the surface finish can be polished to a smoothness of 0.5µin.
The machining process of Macor ceramic parts includes steps such as powder-granulation-forming-sintering-finishing-inspection-cleaning. The thermal expansion coefficient of this material is similar to that of most metals, making it easy to combine and seal with metal parts. In addition, it also has low thermal conductivity (1.71 W/(m · K)), good thermal shock stability (Delta T 200 ° C), extremely high electrical insulation strength (30 KV/mm) and volume resistance (10 ^ 16 Ω · cm), and does not absorb water and has zero air permeability.

Application field
(1) Aerospace field
Macor ceramic parts are widely used in the aerospace industry, such as door and window hinge points, fixed rings, electronic component brackets, high temperature sensor components of space shuttle orbiters, etc. It can effectively prevent heat transfer, while having radiation resistance and non-porosity, ensuring stability and safety in space environments.
(2) Semiconductor and electronics industries
Macor ceramics have close coefficients of expansion to polymers such as metals, glass, and epoxy resins, and can be welded to metals after metallization. It is used in arc-shaped, ultra-thin special-shaped plates and various packaging material combinations in the electronics industry. It can also be customized for coil frames, insulating parts for testing equipment, molds, and fixtures. In addition, the chemical properties of Macor ceramics are close to that of silicon elements, and do not absorb any substances. They can be used in parts that are in direct contact with silicon elements.
(3) Medical field
Macor ceramics are non-toxic and biocompatible, and their chemical inertness, precision machinability, and dimensional stability make them ideal for insulating structures for medical devices and implantable electronic components. For example, it can be used to make key components for high-end B-ultrasound testing equipment.
(4) High-pressure and ultra-high-pressure environments
The dielectric strength of Macor ceramics can reach 45kV/mm at room temperature, and the insulation effect is stable at high temperature. It is suitable for making high-voltage and ultra-high-voltage insulation parts, such as plasma film sample insulation brackets, vacuum coating equipment parts, etc.
(5) High-end instrumentation
Macor ceramics can be used for various equipment structural parts that require complex design, precision machining, and high temperature insulation environments, such as wall coil brackets, thermal insulation pads, guide rails, tools, molds, consumable parts, etc. It is also suitable for special equipment parts with ultra-low temperature and frequent heat and cold changes, such as superconducting components and nuclear magnetic resonance components.
(6) Chemistry and chemical industry
Macor ceramics are chemically inert, do not absorb chemicals, are not easy to age compared to polymers, have a long service life, withstand various organic solvents, and are more resistant to acid and alkali corrosion than ordinary ceramics. It can be used for electrode supports, core corrosion insulation, insulation, high temperature and sealing components in chemical equipment.
(7) Other fields
Macor ceramics can also be used for core sealing components and peripheral accessories in laser generator reflection sleeves, laser cutting and welding ceramic rings, etc. In ultra-high vacuum environments, it can be used for optical communication components, insulating components for field ion microscopes or wire supports and vacuum channels.
