Method and apparatus for material densification or material assembly consolidation by hydrothermal or solvothermal sintering

摘要

The present invention relates to a method and a device for the densification of a material or the consolidation of an assembly of materials, wherein a uniaxial force and a sintering temperature are applied to a humidified material or a humidified assembly arranged in the chamber (11). ) In a single sintering step, the force being applied by at least two pistons (12) movable towards each other in the chamber (11), each piston being With a housing (14) for collecting the fluid discharged into the chamber, the assembly consists of a chamber (11) and a piston (12), the sintering process being carried out entirely in a liquid or supercritical fluid medium. To be sealed.
