REACTION VESSEL FOR GROWING SINGLE CRYSTAL AND METHOD FOR GROWING SINGLE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To prevent swelling and infiltration of a reaction vessel due to the flux within the reaction vessel even when a single crystal is grown at high temperature, in growing the single crystal by using the flux containing sodium metal etc.

SOLUTION: In the reaction vessel 25 used for growing the single crystal by using flux containing at least either of alkali metal and alkaline earth metal, there is provided the reaction vessel 25 composed of ceramics containing either or both of titanium nitride and zirconium nitride as a principal component.
