Abstract
The invention involves a method of making a holder of solid ceramic material by locating a core in a mass of particulate ceramic material, consolidating the particulate material around the core, removing the core from the particulate material to leave a green artifact having a cavity, and sintering the green artifact. The core is shaped and the particulate material is arranged such that the core is in the form of a thin slab between a pair of layers of the particulate material. After sintering, the cavity comprises a thin gap between opposed plates of sintered ceramic material. The slab has openings therethrough which are filled with the particulate material, which, after sintering, forms a bridge across the gap, between the associated plates and sintered thereto.
