Mica Base Machinable Ceramics Products Title
 
Photoveel
 

characteristic of Photoveel

Photoveel is a high density and high quality compound mica ceramics which is produced by a fusion process. The process uses glass as matrix and then precipitated mineralized fluorine phlogopite and zirconia microcrystal. The ceramics are easy to be machined by a lath, drilling machine and machining center etc, and has superior electrical and heat insulation properties. And also it is high dense and low out gas property in vacuum environment．
