摘要:
A method for sintering a metal powder, a ceramic powder, or a mixture thereof accomplishes compact sintering of even a high melting substance by heating the powder at an elevated temperature for a short time under not less than 10,000 atmospheres of pressure. To attain the quick high-temperature heating under the ultrahigh pressure, a Thermit reaction is generated in an ultrahigh pressure generating apparatus which is provided with a gasket made of pyrophyllite and cylinders and anvils protected with heat insulators.For the purpose of preventing the Thermit reaction from inducing a reaction between the Thermit composition and the powder under treatment and the heater and ensuring electrical insulation of these components, barriers made of hexagonal boron nitride and/or tantalum are suitably disposed within the apparatus.
