PURPOSE:To provide a Si-SiC shelf plate having high strength so that the amt. of material to be calcined is increased, and has excellent spalling resistance, creeping resistance and oxidation resistance. CONSTITUTION:This Si-SiC shelf plate consists of a Si-SiC sintered body containing at least SiC and Si as the structural components, and has slits or grooves to relax stress. These slits or grooves are filled with metal Si. This Si-SiC shelf plate is obtd. by using such a source material containing SiC powder, org. binder, water or org. solvent, and if necessary, graphite powder, compacting the source material into a body having slits or grooves, impregnating the compact with metal silicon in an inert gas atmosphere under reduced pressure or in vacuum, and filling the slits or grooves with the metal silicon. |
