<p>The present invention provides: a gas, which an oxidizing gas is difficult to break inside; a firing container; and a manufacturing method for preventing the oxidation of a fired material. Also, the present invention relates to a gas, which has an opening in the upward direction and covers the opening with a cover for being used for firing a graphite material. The present invention provides: the gas, which has grooves supporting the cover along the outer periphery of the opening or the inner circumference; a firing container, which has a cover and a frame unit fitted with the gas and the grooves; and a manufacturing method of a graphite material for putting the shaped body of the graphite material in the gas, for closing the frame unit of the cover to be immersed into the grooves of the gas, and for filling a powdered or granular filler into the grooves and firing the shaped body.</p> |
