Zirconia setter plate, MnZn ferrite, and method for producing same
Provided are: a zirconia setter plate capable of producing a ferrite having a high relative initial permeability and a high Curie temperature; a MnZn ferrite produced using the setter plate; and a method for producing the MnZn ferrite. A zirconia setter plate having a CaO content of 0.28 mass% or less and a porosity of 45.0 vol% or less. Also disclosed is a method for producing a MnZn ferrite, which uses the zirconia setter plate to produce a MnZn ferrite that is mainly composed of Fe2O3, ZnO, and MnO. The MnZn ferrite is produced by the production method, and in a sintered body obtained by sintering the MnZn ferrite raw material, the ZnO content of the setter plate ground plane is 95.0% or more with respect to the ZnO content inside the sintered body.
本发明提供一种能够制造具有高相对初始磁导率和高居里温度的铁氧体的氧化锆质承烧板、使用该承烧板制造的MnZn系铁氧体及其制造方法。一种氧化锆质承烧板，CaO的含量为0.28质量％以下，气孔率为45.0体积％以下。一种MnZn系铁氧体的制造方法，使用所述氧化锆质承烧板来制造以Fe2O3、ZnO和MnO为主成分的MnZn系铁氧体。一种MnZn系铁氧体，该MnZn系铁氧体是使用所述制造方法制造的，在通过烧结MnZn系铁氧体原料而得到的烧结体中，相对于所述烧结体内部的ZnO含量，承烧板接地面的ZnO含量为95.0％以上。
