Title:

MANUFACTURE OF HIGH STRENGTH SILICON CARBIDE SINTERED BODY

Document Type and Number:

Japanese Patent JPS57209884

Kind Code:

A

Abstract:

A method for producing a high strength sintered silicon carbide, the method comprising: molding a mixture of silicon carbide powder and a sintering aid into a green compact of a predetermined shape: preliminarily sintering the green compact to obtain a preliminarily sintered compact having a relative density higher than 80%; charging the preliminarily sintered compact in a HIP equipment without using a capsule; and subject the preliminarily sintered compact to a HIP treatment in a high-temperature and high-pressure N2 gas atmosphere maintaining a pressure higher than 500 atms and a temperature in the range of 1400 DEG -2300 DEG C.
