METHOD FOR PRODUCING CA-LA-F-BASED LIGHT-TRANSPARENT CERAMIC, CA-LA-F-BASED LIGHT-TRANSPARENT CERAMIC, OPTICAL MEMBER, OPTICAL SYSTEM, AND COMPOSITION FOR CERAMIC FORMATION |
| 摘要 |
<p>This invention provides a method for producing a Ca-La-F-based light-transparent ceramic, comprising mixing fine particles of CaF2 with fine particles of LaF3 prepared separately from the fine particles of CaF2 to prepare a fine particle mixture and sintering the fine particle mixture to render the mixture transparent to light.</p> |
