To provide a firing fixture capable of diffusing a binder upon heat treatment.SOLUTION: A firing fixture 1 performs heat treatment in such a manner that the object 2 to be fired is mounted in a state where the bottom face 2b of the object 2 to be fired is abutted against a mounting face 1a, comprises: a base part 12; and a projecting part 13, in which, the mounting face 1a is formed in such a manner, when the object 2 to be fired is mounted on the mounting face 1a, an abutting face part and the face part to be abutted are provided, the area of the abutting face part is formed so as to be smaller than that of the face part to be abutted, provided that the porosity of the base part 12 is defined as 1, the porosity of the projecting part 13 is above 1 to 1.75, and, regarding the value of the heat expansion coefficient of the base part 12 and the heat expansion coefficient of the projecting part 13, provided that either smaller heat thermal expansion coefficient is defined as 1, the other higher one is 2.48 or lower. In the firing fixture 1, even if a gas in a binder or the like is transpired from the object 2 to be fired upon the heat treatment, the gas is diffused into the space of the face part to be abutted, and defects caused by the gas can be suppressed.SELECTED DRAWING: Figure 2
【課題】熱処理時にバインダを拡散できる焼成治具を提供すること。【解決手段】本発明の焼成治具１は、被焼成物２の底面２ｂを、載置面１ａに当接した状態で載置して熱処理を行う焼成治具１であって、基部１２と突出部１３とを有し、載置面１ａに被焼成物２を載置したときに、当接面部と非当接面部と、を有するように載置面１ａが形成され、当接面部の面積が、非当接面部の面積より小さく形成され、基部１２の気孔率を１としたときの、突出部１３の気孔率が１より大きくかつ１．７５以下であり、基部１２の熱膨張係数と突出部１３の熱膨張係数の値が、小さい一方の熱膨張係数を１としたときに、大きい他方が２．４８以下であることを特徴とする。本発明の焼成治具１は、熱処理時に被焼成物２からバインダ等のガスが蒸散しても非当接面部の空間にガスが拡散し、ガスによる不具合が抑えられる。【選択図】 図２
