METHOD FOR PRODUCING GALLIUM OXIDE SINGLE CRYSTAL AND GALLIUM OXIDE SINGLE CRYSTAL

PROBLEM TO BE SOLVED: To provide a method for producing a gallium oxide single crystal, by which a gallium oxide single oxide having a larger size is mass-produced efficiently by a batch production system comprising bringing a seed crystal into contact with a melt and growing a crystal by using an existing growth furnace without remodeling the furnace. SOLUTION: In the method for producing a gallium oxide single crystal, the gallium oxide single crystal 13 is produced through at least a density-enhancing process of highly enhancing the density of a raw material containing gallium oxide, a melting process of obtaining one batch of melt 2 by melting the raw material treated in the density-enhancing process, in a crucible, and a crystal growth process of growing the gallium oxide single crystal 13 from the melt 2 by bringing the seed crystal 10 into contact with the melt 2.
