Abstract
A process for preparation of capsule for use in isostatic pressing treatment, the process comprising a first step of enclosing a material to be treated, such as ceramic, metal, resin, etc. with metallic foil having a thickness of from 30 to 300 .mu.m, and a second step of welding the metallic foil so as to seal the material to be treated in the metallic foil thus welded, thereby preparing a capsule, wherein the welding is carried out by means of TIG welding. Alternatively, the welding may be carried out by means of seam resistance welding. It is posible, by the process, to seal the material to be treated in a capsule easily and economically. The capsule thus obtained is in a good sealed condition, permits effective isostatic pressing treatment, and enables the treated material to be taken out easily. A ceramic or metal layer covers the material to be treated to prevent adhesion between the material and the metallic foil.
