    摘要: A composite ceramic is produced by forming a mixed powder of Si and a compound oxide as the starting material into a formed material, nitriding and firing the formed material to form a sinter, and subjecting the sinter to oxidation treatment. The composite ceramic, which is:lightweight and reduced in heat conductivity, has a specific gravity of at most 2.6, and comprises a phase composed of all of elements Si, O and N, and at least one element selected from the element group consisting of A1, Zr, Li, P and Mg, in which phase a subphase composed of Si, Al, 0 and N and a subphase composed of Si, O and N are formed. Another composite ceramic has pores and a disperse phase in a matrix phase composed of Si.sub.3 N.sub.4 crystal grains, an oxide and an oxynitride, and further comprises coarse Si.sub.3 N.sub.4 grains dispersed in the matrix phase with O-containing boundary reaction product layers formed in the boundaries between the matrix phase and the coarse Si.sub.3 N.sub.4 grains. Thus, this composite ceramic, though reduced in heat conductivity, has a high toughness and a high strength due to dispersion of the coarse Si.sub.3 N.sub.4 grains in the matrix phase.

The slidable ceramic member is used as a slidable component of a heat engine such as a cylinder liner or a piston ring which is subjected to repeated thermal stresses. Such a slidable ceramic member is manufactured by placing powder of a fluoride including elements belonging to group IIa of the periodic table on a surface of a base, and heating the base while rubbing the powder against the surface of the base, whereby the silicon (Si) contained in the base and the group-IIa elements contained in the powder can react with each other, thereby forming a slidable layer on the surface of the base.
