Abstract
PURPOSE: To prepare simply the product having excellent precision of dimensions, by using the metal salt as the material for the mold, when the special form material of complicated shape is prepared with the sintering of diffusion joining by means of the hot hydrostatic pressure method.
CONSTITUTION: The mold material 1 is made of the metal salt such as chloride such as NaCl, KCl, etc. sulfate such as Na2SO4, CaSO4, etc. or nitrate such as NaNO3, KNO3, etc. The metal powder, ceramic powder, etc. 2 is filled in the mold material. After having placed the cover 3 made of the same material on its upper face, the mold material is charged into the metallic capsule 4, is degassed in vacuo and is sealed hermetically. While heating this below the melting point of the metal salt of mold material, the mold material is pressurized with the hot hydrostatic pressure and is compressed to the density above 90%. Then, the metal capsule 4 is placed in the furnace of high temperature and high pressure and is pressurized with the hot hydrostatic pressure, so that the mold material 1 is melted and is transformed according to the shape of the molded product to the molded. Because the mold material is the metal salt, the preparation is easy and the complicated special form molded product having good workability and excellent precision of diemensions, is obtained.
