Title:
SINTERING PROCESS
Document Type and Number:
WIPO Patent Application WO/1986/004890
Kind Code:
A1
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.
