If it is less than 5%, the effect of improving strength is poor, and if it is more than 60%, the density of the sintered body becomes small and there are many pores, and the strength decreases. The whiskers are preferably made of silicon carbide or silicon nitride, and the shape is related to both diameter and length, preferably 2 to 15 μm on average. If it is less than 2 μm, the effect of improving strength is poor, and if it exceeds 15 μm, it is difficult for whiskers to disperse in the ceramic during molding, and pores remain in the sintered body, resulting in a decrease in strength. The closer the angle of the whiskers dispersed in the ceramic is to the axis, the stronger the strength will be, and the effect is particularly large around 150°, but those oriented up to 1o0 or 5° have particularly high strength. .

The same process was repeated to form a rod-shaped body, which was then hot-pressed in nitrogen at 1800°C for 8 hours to obtain a thickness of 4mm, a width of 8mm, a length of 25mm, and a transverse rupture strength. was measured. The results are shown in Table 1. In addition, the bending strength was clearly increased at an angle of 150 or less, where 80% or more of the whiskers were axes, and at a whisker content of 5 to 60%.
