HEAT TREATMENT SETTER COMPOSED OF CERAMIC SINTERED BODY WITH IRREGULARITIES PROCESSED SURFACE
To provide a high functional heat treatment member that can suppress deformation and crack of an electronic component after firing even when producing a downsizing and high performance electronic component or the like by firing, and suppress, when using it for a vessel to synthesize high functional powder, a reaction between the vessel and the synthetic powder and sticking.SOLUTION: A heat treatment member includes irregularities satisfying following requirements a) to d) on a surface, and is composed of any of an alumina sintered body, a magnesia sintered body, a mullite sintered body, and spinel sintered body. The requirements include that: a) a maximum height Ry of convex parts of the irregularities is not more than 30 μm; b) a width of the convex parts of the irregularities is not more than 120 μm; c) the difference between the maximum height and the minimum height of the convex parts of the irregularities is not more than 15 μm; and d) there are 30 to 200 pieces of the convex parts of the irregularities within the area of 1 mm2 of the surface.SELECTED DRAWING: None
