Calcium Fluoride CaF2 Physical and Chemical Properties
WebNov 1, 2004 · Single-crystal CaF2 is an important optical material. In this work, single-point diamond turning experiments were performed to investigate the nanometric machining characteristics of CaF2. The effects of tool feed, tool rake angle, workpiece crystal orientation and cutting fluid were examined. It was found that two major types of … WebIn this study, we proposed a new technique for the purification of CaF2 sludge by selectively carbonating sulfate contaminants (mainly gypsum). First, we demonstrated the dissolution of gypsum and fluorite in Na2CO3 solution and examined the dissolution kinetics by adapting a shrinking core model. Webfor Polishing CaF2 and KDP Magnetorheological finishing (MRF) is a novel and recently commercialized1 process for figuring and polishing plano, convex, and concave optics—both spherical and aspherical— from a wide variety of optical materials.
