Abstract

PURPOSE: To intend to make the electric wave absorptive body a thnner type having a high bondwidth by dispersing a powder mixture consisting of powders of ferrite and of magnetic which can be represented by a special general formula.
CONSTITUTION: A powder mixture consisting of powders of ferrite (Fe3O4) and of magnetite represented by a general formula MOFe2O3 (wherein M is more than one kind of Mn, Ni, Mg, Co, Cu and Zn) is dispersed in a high molecular organic material. The ratio of weight % between powders of ferrite and of magnetite is preferable to be within a range of 1:05 to 1.4 and the ratio of volume % of the magnetite powder mixture thereof is also desirable to be 24 to 34 %. For instance, a wall for electric wave absorption is made by painting a composite material having 2.25 mm in thickness of an electric wave radiant body made of aluminum plate after paintnizing said composite material by mixing and dispersing the mixing powders having the ratio of 1:1.3 by weight % between ferrite powders and NiMgZn powders in the chloroprene rubber.
