assignmentn n n n The shape which has comparatively large thickness, without carrying out complex heat treatment, and the manufacturing method which can shift a Curie temperature to a positive direction without using Pb, and obtains the semiconductor ceramic composition which reduced the resistivity at room temperature significantly. Also in the material of the present invention, there is provided a method for producing a semiconductor ceramic composition, which can give uniform properties to the inside of the material.n n n n Resolutionn n n n The composition formula is represented by [(Bi 0.5 Na 0.5 ) x (Ba 1-y R y ) 1-x ] TiO 3 (wherein R is at least one of La, Dy, Eu, Gd, and Y), wherein x and y are , 0 <x ≦ 0.14 and 0.002 ≦ y ≦ 0.02, wherein the sintering is carried out in an inert gas atmosphere having an oxygen concentration of 1% or less, thereby significantly reducing the resistivity at room temperature. It gives uniform properties to the inside of the material. |
