    摘要: A casting apparatus including a die that contains a molten metal that is poured via an opening section disposed above the die. The casting apparatus also includes a heater disposed above the die, and a gas supplying structure for supplying an inter gas to a surface of the molten metal. The casting apparatus further includes a lid disposed between the surface of the molten metal and the heater, and a lid moving structure for moving the lid to the die relatively so as to control the opening amount of the opening section above the die.

    摘要: This metallic silicon is manufactured by refining molten crude metallic silicon by unidirectional solidification, and has a purity of 3N or more to 6N or less and an average crystal grain diameter of 1 mm or more. This method for manufacturing the metallic silicon includes: solidifying molten crude metallic silicon in a mold which contains fine silica particles in an inner peripheral layer thereof by unidirectional solidification at a rate of 1 mm/min or less; and then cooling to 200° C. or below at a rate of 2° C./min or less.
