Macro microcrystalline glass ceramic structural components

MACOR microcrystalline glass ceramic structural component is a high-performance material produced by Corning Incorporated in the United States, mainly composed of fluorobiotite and borosilicate glass. This material forms a polycrystalline structure through a special crystallization modification process, combining the advantages of glass and ceramics.

Significant characteristics:
-Excellent processing performance: ordinary metal processing equipment can be used for drilling, turning, milling, grinding, sawing, polishing and other processing, with a processing accuracy of ± 0.013 millimeters and a surface smoothness of less than 0.5 microns.
-High temperature stability: The continuous use temperature can reach 800 ℃, and the peak temperature can reach 1000 ℃.
-Excellent electrical insulation: The dielectric strength of the 0.3mm thick material can reach 45kV/mm at room temperature, and the volume resistivity can reach 10 ^ 14 to 10 ^ 15 ohms/cm.
-Low thermal conductivity and high thermal shock resistance: The thermal conductivity is about half that of alumina ceramics, and it will not break even from 800 ℃ to 0 ℃.
-Chemical stability: It has excellent corrosion resistance to most chemical substances (except hydrofluoric acid and molten alkali metals).
-Vacuum compatibility: The gas release rate is below 1 × 10 ⁻⁹ Torr · L/s · cm ², and the porosity is zero.
