6 FERROMAGNETIC DIELECTRIC SUBSTANCE Authors of the Invention: Yu. G. Borzyak, N. N. Oster-Volkov, A. I. Rolik, and A. I. Yakovlev A large variety of ferromagnetics and magnetodlelectrics has been widely used in high-frequency equipment, where they occupy a leading position. The use of ferromagnetics in low-frequency equipment of powerful currents (for electrical machine building) is limited only by metallic ferromagnetics, for example, silicon steels, since the ferromagnetic dielectrics, together with good magnetic and dielectri-c-qualities must have good strength characteristics and.high heat resistance. The known use of the mixture of magnetically soft iron powder with a polymer thermoreactive compound as a binder is by itself assumed as a basis of the proposed ferromagnetic dielectric substance. To obtain a substance which possesses high heat resistance, as the indicated compound it is proposed to use the compound of furan epoxy resin with an addition of a hardner (hexamethylene diamine or polyethylene polyamine) and a fiberglass admixture. The weight ratio of the ingredients making up the composition of the substance is determined by the following limits: iron powder with a dimension of m parts, furan epoxy resin parts, hardener (hexamethylene diamine or polyethylene polyamine parts, and admixtures of glass fiber parts. The iron powder is carefully mixed with the resin and the admixture in the portions indicated for minutes up to complete wettability of all particles of the powder, after which the hardener is introduced, and the entire substance is again mixed for 5-10 minutes until complete uniformity is obtained. The preparatory mixture is a casting composition for obtaining final articles of necessary shapes. The casting molds are aged for hours at normal temperature 1

7 and then undergo hot hardening according to the following conditions: at 80 0 C hours, at C hours, at C hours, and at C - 2 hours. To obtain the physicomechanical properties of the articles, it is necessary to give an additional holding at C for 5-6 hours. The viability of the casting composition of the substance with the hardener hexamethylene diamine is minutes and with the hardener polyethylene polyamine, hours. Clim of the Invention he claim of the invention is a ferromagnetic dielectric substance on the basis of a magnetically soft iron powder and polymer thermoreactive compound as the binder, which differs in that for the purpose of ensuring high heat resistance and mechanical strength, the compound indicated consists of a furan epoxy resin with the addition of a hardener (hexamethylene diamine or polyethylene polyamine) and a fibergfais admixture 2
