PURPOSE:To obtain a uniformly dried sintered product by calcining a plate- shaped material to be sintered with at least the lower surface held by a specific calcination jig. CONSTITUTION:The lower surface of both the lower and upper surfaces of a plate-shaped material 4 to be sintered is (are) held by a calcination jig 3 consisting of plate-shaped porous structure with its one surface provided with a metallic coating 9, and the resulting system is put on a scaffold 8 set in a sintering furnace and heated by heaters 1, 4 from above and below, respectively, and calcined while feeding dry air through blast ports provided on a quartz muffle 2. |
