IMPREGNATION CRUCIBLE
To provide an impregnation crucible which has improved use life.SOLUTION: A method for manufacturing an impregnation crucible includes: a depressurization step (A) of putting a reduced and fired crucible material 10 into an empty impregnation tank 11 and depressurizing inside of the impregnation tank 11; a filling step (B) of filling the depressurized impregnation tank 11 with an antioxidant solution 12 through a conduit 14 from a solution tank 13; a pressurization step (C) of pressurizing the inside of the impregnation tank 11 filled with the antioxidant solution 12, and impregnating a pore of the crucible material 10 with the antioxidant solution; and an opening step (D) of impregnating the pore with the antioxidant solution in the impregnation tank 11 and then opening the impregnation tank 11 to the air, and simultaneously returns the antioxidant solution 12 to the solution tank 13 through the conduit 14 from the impregnation tank 11 and takes out the crucible material 10 from the impregnation tank 11.SELECTED DRAWING: Figure 1
【課題】使用寿命の向上を図った含浸坩堝を提供すること。【解決手段】含浸坩堝の製造工程は、空の含浸槽１１に還元焼成した坩堝材料１０を入れて含浸槽１１の内部を減圧する減圧工程（Ａ）と、減圧した含浸槽１１に溶液タンク１３から管路１４を通して酸化防止溶液の溶液１２を充填する充填工程（Ｂ）と、酸化防止溶液の溶液１２を充填した含浸槽１１の内部を加圧して坩堝材料１０の気孔中に酸化防止溶液を含浸させる加圧工程（Ｃ）と、含浸槽１１で気孔中に酸化防止溶液を含浸させた後、含浸槽１１を大気に開放するとともに、含浸槽１１から管路１４を通して酸化防止溶液の溶液１２を溶液タンク１３に戻し、含浸槽１１から坩堝材料１０を取り出す開放工程（Ｄ）を備える。【選択図】図１
