Abstract
The high-strength and high-toughness sinter of the present invention comprises a crystal agglomerate maintaining a fibrous shape and composed of crystals of SiC and MC.sub.1-x wherein M is Ti and/or Zr and X is a number of 0 or more but less than 1. This sinter is produced by laminating an inorganic fiber comprising a particular inorganic material containing titanium and/or zirconium molding the laminate into a predetermined shape, and conducting heat-sintering simultaneously with the molding or after the molding in an atmosphere comprising at least one member selected from the group consisting of a vacuum, an inert gas, a reducing gas, and a hydrucoarbon gas at a temperature of 1,700.degree. to 2,200.degree. C.
