Abstract
PURPOSE: To prepare simply the product having excellent precision of dimensions, by using the refractory substance and water glass of binder 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 slurry obtained from sulfate, chloride or nitrate such as CaSO4, NaCl, etc. or refractory material such as Al2O3, SiO2, etc. by using water glass as the binder, or from sand by using water glass or resin as the binder, is made to flow into the mold and is roasted, so as to make the mold material 1. The powdery metal or ceramics 2 is filled in this mold material and is covered with the cover 3 of the same material as the mold material 1. By heating this after the vacuum degassing, the cover 3 is sealed hermetically to the mold material 1. Then, the hot hydrostatic press is performed in the furnace of high temperature and high pressure. Or, the mold material 1 filled with metal powder is placed in the capsule 4, which is sealed hermetically after the vacuum degassing, and the hot hydrostatic press is performed. In this way, the special form product having excellent precision of dimensions is obtained from the powdery raw material.
