摘要： PROBLEM TO BE SOLVED: To provide a vessel with which a polycrystalline silicon ingot having good electrical properties and high photoelectric conversion efficiency can be manufactured.
SOLUTION: The vessel 1 useful for melting silicon has such a tapered shape that the thickness of the bottom part of the side wall 3 is made thick and the thickness of the side wall 3 becomes thinner toward an upper part of the side wall. It is preferable from the viewpoint of the yield of the polycrystalline silicon ingot obtained that the taper angle is 0.5-2°. The biting of silicon is suppressed, the generated stress is easily liberated, the residual amount of internal strain in silicon is reduced, and the photoelectric conversion efficiency of the polycrystalline silicon is improved by making the inner surface of the vessel into such a flat surface that the undulation is ≤3 mm and the surface roughness Ra is ≤10 μm, preferably ≤6 μm.

SOLUTION: The inner face of the molded vessel for melting silicon is coated with a silicon compound or a silicon composite agent and then the molded vessel is fired. Silica powder slurry is poured into a mold to form the vessel, and the vessel is dried. The inner face of the vessel is uniformly coated by an airbrush with water slurry produced by mixing Si 3 N 4 and a dispersion agent. After the water slurry is dried, the vessel is sintered at 1,200°C in a firing furnace so as to obtain the vessel for melting silicon on whose inner face the mold releasing layer excellent in mechanical strength and sinterability is formed.
