ferroferrite of mn, zn, sn - - - ti for a range of temperatures and of extended

摘要

P the invention relates to a ferroferrite of mn, zn, sn - - - ti for a wide range of temperatures and frequency. In this ferroferrite of mn, zn, sn - - - ti, the composition of the initial components is as follows: about 49 to 55% by mole of fe2 o3, 10 to 40% by mole of mno, 0,5 to 5% by mole of (dno2 + tio2), and the remaining in zno, the content of fe * * 2 + in the network of the ferrite is controlled by the percentage of fe2 o3 exceeding 50% by mole and the percentage of the sum of the ingredients of sno2 and tio2 and being chosen in such a way that the ferrite is the loss factor and the temperature coefficient, respectively, desired. A particular application of the ferrites for multiplexing systems at high frequency. / p
