PURPOSE:To obtain a die capable of realizing isotropic pressurization by taking such a system as to pack the pressurizing chamber thereof with fluid spherical particles conduct a pressure sintering with these particles as a pressure transfer medium. CONSTITUTION:This die is a die for uniaxial pressure sintering, having the following system: made up of one or a pair of punch 2,7 each constituted of at least one slope 10(4) with the angle 11 between the pressurizing tip and the pressurizing axis being greater than 15 but smaller than 75; a cylinder 3 having a penetrating open hole for the punch 2,7; and, fluid spherical pressure transfer particles 6(9) packed in the pressurizing chamber formed by the cylinder 3 and the punch 2,7. And, by applying a uniaxial load 1(8) to the punch 2,7, a molded form 5 embedded in the particles 6 is subjected to an isotropic pressure. |
