PURPOSE:To a provide a method for burning ceramics by which the deformation can be avoided; the dispersion in shrinkage factor is extremely small and the resultant sintered compacts are excellent in smoothness and good in density thereof and the dispersion in various characteristics is slight without a deviation of composition by arranging a frame provided with a lid placed on a specific plank having many honeycombed through pores, etc., spreading powder for suppressing the fluctuation in the composition on the plank, placing compacts of the ceramics thereon and baking the ceramics. CONSTITUTION:This method for baking ceramics is to use three kinds of planks respectively having many through pores and the many pores assuming a honeycombed form or bottomed pores assuming the honeycombed form or transverse or vertical grooves as a specific plank and powder having a content of ZnO increased from that of the same composition by, e.g. 0-3mol% as powder for suppressing the fluctuation in composition. This figure is one example of the plank having the many through pores. The plank 2 for baking made of zirconia is used and the many through pores 5 are arranged in the honeycombed form. Furthermore, the powder 13 having the same composition as that of an Mn-Zn-based ferrite is piled up on a bed plate 4 made of zirconia and compacts 10 having the same composition are placed thereon. A frame 11 and a lid 12 are placed to bake the ceramics in an atmosphere of oxygen. |
