Abstract
The encapsulation of ceramic preforms (10) for HIP processing is considerably simplified, and the use of standard laboratory glassware as encapsulation material is made possible, by placing non-sealed glass capsule parts (12, 14) around the preform (10) in the HIP pressure vessel (18), evacuating the vessel (18), heating the vessel (18) to a temperature at which the glass parts (12, 14) fuse together but do not collapse, and then pressurizing the vessel (18) and increasing the temperature therein as required for conventional HIP processing.
