Zero-porosity fluorphlogopite mica glass-ceramic rods, plates, and finished CNC parts that machine with standard metalworking tools with zero post-firing shrinkage.
Fluorphlogopite mica glass-ceramic features randomly oriented microscopic mica platelets dispersed within a borosilicate glass matrix, arresting micro-cracks locally so standard high-speed steel or carbide end mills, drills, and taps can cut tight ±0.013 mm tolerances directly—with zero post-machining kiln firing and zero shrinkage. Unlike porous unfired ceramics, it is 100% dense, non-outgassing in ultra-high vacuum, radiation-resistant, and continuous-rated to 800 °C (1,000 °C peak).
Ideal for fast-turn R&D prototypes, UHV feedthrough blocks, coil forms, synchrotron/beamline fixtures, and aerospace/medical test jigs.

Reference values reflect typical sintered, fused, or wrought grades. Exact batch test figures are confirmed on your written quotation and accompanying lot Certificate of Analysis.
Specify raw blank dimensions (rod diameter × length or plate L × W × thickness) for in-house machining, or provide a 3D STEP / 2D PDF drawing with thread callouts for finished CNC-machined components.
Include target quantity, destination country/postal code for express air freight calculation, and any special cleanroom bagging or certification requests.
