Ca-La-F BASED TRANSPARENT CERAMIC, Ca-La-F BASED TRANSPARENT CERAMIC, OPTICAL ELEMENT, OPTICAL SYSTEM, AND CERAMIC-FORMING COMPOSITION

摘要

A Ca—La—F based transparent ceramic, including: mixing CaF₂ particles and LaF₃ particles that are prepared separately from the CaF₂ particles to form a mixed body of particles, and sintering the mixed body of particles and making the mixed body transparent, thereby producing a transparent ceramic.
