一种用于热液法晶体生长的变口径高压釜
摘要：
本发明公开了一种用于热液法晶体生长的变口径高压釜，包括釜体，釜体内腔存在溶解区和结晶区，所述釜体内结晶区的口径大于所述釜体内溶解区的口径。本发明将釜体内腔中结晶区的口径设计成大于釜体内腔中溶解区的口径的结构，一方面，与同样高度及外径的传统高压釜相比，增加了高压釜釜体内腔的容积，可以使晶体在同一个釜体内多周期连续生长，克服了频繁更换高压釜存在的诸多问题，还可以节省成本；另一方面，釜体内结晶区位于溶解区的上方，且结晶区的口径大于溶解区的口径，有效减缓釜体内腔中气液对流的剧烈程度，更有利于晶体的生长，还可以增加结晶区营养盐的载入量。
摘要（英）：

The invention discloses a variable-diameter autoclave for hydrothermal method crystal growth. The variable-diameter autoclave comprises an autoclave body, a dissolving area and a crystallizing area are located in an inner cavity of the autoclave body, and the diameter of the crystallizing area in the autoclave body is larger than that of the dissolving area in the autoclave body. The variable-diameter autoclave has the advantages that due to the structure that the diameter of the crystallizing area in the inner cavity of the autoclave body is designed to be larger than that of the dissolving area in the inner cavity of the autoclave body, on one hand, compared with a traditional autoclave with the same height and outer diameter as the variable-diameter autoclave, the capacity of the inner cavity of the autoclave body is increased, crystals can continuously grow in the same autoclave body in multiple periods, a lot of problems caused by frequent replacement of autoclaves are solved, and cost can also be saved; on the other hand, the crystallizing area in the autoclave body is located above the dissolving area, the diameter of the crystallizing area is larger than that of the dissolving area, the intensity of gas-liquid convection of the inner cavity of the autoclave body is relieved effectively, crystal growth is facilitated, and the loading quantity of nutritive salt in the crystallizing area can also be increased.
