PURPOSE:To provide a porous jig for burning capable of preventing Zn from evaporating in burning an Mn-Zn-based ferrite. CONSTITUTION:This porous jig for burning is a porous material, having open cells and obtained by impregnating the holes with a ferrite slurry of the same material as that of a ferrite compact to be burned and then drying the impregnated compact. |
