Abstract:
A method of producing 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.
