Isostatic pressing

  "id": "MLC-T-CHM-013223",
  "term": "Isostatic pressing",
  "field": "Chemistry",
  "definition": "A materials processing method where a powdered or porous preform is compacted by applying uniform pressure from all directions. The component is sealed in a flexible container and submerged in a fluid medium, such as water or oil for cold pressing or an inert gas for hot pressing, which is then pressurized. This technique produces a densified object with very uniform density and a fine, homogeneous microstructure, minimizing internal stresses and warping compared to uniaxial pressing.",
