METHOD FOR PRODUCING Ca-Gd-F-BASED TRANSLUCENT CERAMIC, Ca-Gd-F-BASED TRANSLUCENT CERAMIC, OPTICAL MEMBER, OPTICAL SYSTEM AND COMPOSITION FOR MOLDING CERAMIC

摘要

PROBLEM TO BE SOLVED: To provide a Ca-Gd-F-based material having high Abbe number comparable with that of fluorite and having a refractive index higher than that of fluorite as a translucent ceramic.;SOLUTION: The translucent ceramic is produced by mixing CaF₂ fine particle and GdF₃ fine particle produced separately from the CaF₂ fine particle to prepare a fine particulate mixture and sintering the fine particulate mixture to make the sintered mixture transparent.;COPYRIGHT: (C)2011,JPO&INPIT
