Abstract

PURPOSE:To grow a crystal by providing a temp. gradient to phosphoric acid as a medium, placing rare earth element phosphate in the acid at one side where the solubility of the phosphate is higher and a seed crystal at the other side, carrying the phosphate toward the seed crystal after dissolution, and coagulating it on the seed crystal. CONSTITUTION:A heating wire 1b is wound around the heat insulating container 1a of a heating apparatus 1 in the longitudinal direction. A quartz reaction tube 2 is set in the apparatus 1, and an oblong crucible 3 of pure gold or the like with superior resistance to phosphoric acid is set in the tube 2. The crucible 3 is filled with phosphoric acid 4 as a medium, rare earth element phosphate 5 as starting material and a seed crystal 6 are placed in the crucible 3 at one end and a part away from the end, respectively, and the crucible 3 is tightly sealed with a lid 7. A temp. gradient is then provided to the acid 4 with the wire 1b so that a temp. section where the solubility of the phosphate is higher and a temp. section where the solubility is lower are formed at the phosphate placed part and the seed crystal placed part, respectively. The phosphate is dissolved, carried, and coagulated on the seed crystal 6 to grow a crystal.
