Abstract: A ceramic sinter is produced by utilizing the heat of reaction of the thermit process as the heat source, wherein a preheating step precedes a sintering step, or a mixture of: (A) at least one ceramic powder, (B) at least one nonmetallic powder selected from the group consisting of carbon, boron and silicon powders, and (C) a metal powder and/or a nonmetallic powder other than the above-mentioned powder (B), is used as the raw material. This method gives homogeneous dense ceramic sinter and composite ceramic sinter. Furthermore the fine textures of the sinter and the composition and distribution of the composite ceramic phase can appropriately be controlled thereby.
