    摘要: A honeycomb structure according to the present invention has partition walls, and a number of through-holes divided from each other by the partition walls and extending in an axial direction. The honeycomb structure contains silicon carbide (SiC) or a composite material having silicon carbide (SiC) as a main crystal phase, and has a cylindrical shape. A circularity of a periphery of the honeycomb structure is in a range of 1.0 to 2.5 mm. The honeycomb structure can be contained in a metal container in stable state and hardly has problems such as breakage or breakdown.

    摘要: A ceramic jig for hot rolling is a sintered body consisting essentially of Si.sub.3 N.sub.4, a sintering aid and trace amounts of impurities. In the ceramic jig, crystallization is made among the Si.sub.3 N.sub.4 grains, and a crystalline phase among the grains comprises 80% or more of a J phase, 10% or less of an H phase and 5% or less of a K phase. A reaction of a jig component with iron and water can be inhibited, and the wear of the jig at the time of rolling can be reduced. The seizure of the jig on a steel material does not occur, so that scratches on products can be remarkably reduced.
