１）２を見出した。Problems with the growth of colored crystals using conventional hydrothermal synthesis methods, such as color tone, color unevenness, transparency, or the occurrence of cracks, are caused by the selection of coloring additives. There are various types of coloring additives, but Co(01) is the most suitable coloring additive to solve the above problems.

用添加剤してＣｏ（Ｏｆｆ）ｚを用いた。In the hydrothermal synthesis method, starting materials are placed in a container (in an aqueous solution of an appropriate solvent) at an appropriate temperature and pressure, and the crystals are seeded by slowly cooling them or by transporting nutrients using the temperature difference. Cultivate above. A coloring additive is added during this crystal growth. As a result, the coloring additive turns into metal ions in the water container and is incorporated into the crystals. Co(Off)z was used as the coloring additive.
以下、実施例に従い詳しく説明する。Hereinafter, a detailed explanation will be given according to examples.

な構成の圧力容器中で着色水晶の育成を行った。The pressure vessel main body 1 is pressure-sealed by a cover 3 via a seal ring 2. In the pressure vessel having the above configuration, the growth raw material 4 and the coloring additive Co(OH) 28 are installed at the bottom of the pressure vessel main body. As the raw material 4 for growth, a natural crystal raw stone (rath force) crushed into an appropriate size was used. Next, a seed crystal 6 is placed on the growth raw material 4 via a seed crystal support frame 5 . As the seed crystal 5, natural or artificial crystal is used. There are various crystal planes of the seed crystal (for example, 2 planes, 7 planes, R planes, etc.)
is used, but this time I used a two-sided one (Z tentative). In addition, a seed crystal with few internal inclusions, cracks, dislocations, etc. is required so as not to cause defects in the single crystal to be grown. In this way, the training source zero 4
4 and a seed crystal 6 are arranged, and a temporary hashable 7 is installed between them via a seed crystal support frame 5 as well. Colored crystals were grown in a pressure vessel with such a configuration.
