PURPOSE:To readily remove a glass capsule from a sintered compact after hot isostatic pressing by arranging metallic wires on the surface of a powder compact, performing hot isostatic pressing treatment of the compact, carrying out electrical conductive heating of the metallic wires and then forming cracks in the glass capsule. CONSTITUTION:Metallic wires 18 are arranged on the surface of a powder compact 30. In this state, the aforementioned powder compact 30 is covered with a glass capsule 26. The aforementioned compact 30 covered with the glass capsule 26 is subsequently hot isostatically pressed and sintered under pressure. After the sintering, a current is repeatedly passed through the above-mentioned metallic wires 18 to rapidly heat the aforementioned capsule 26 and form cracks therein. The above-mentioned capsule is then readily removed. |
