Abstract: A process for densely sintering metal powder, ceramic powder or a mixture thereof by conducting high-temperature heating in a short time under a super-high pressure of 100,000 atm or above. The high-temperature heating is conducted by causing a thermit reaction within a super-high pressure-generating apparatus equipped with a pyrophyllite gasket and a cylinder and an anvil having a heat insulator. Hexagonal boron nitride and/or tantalum barriers are arranged in place in the apparatus for preventing any reaction between the resulting thermit composition and sintered powder or heater and for electric insulation.

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.
