The aim of work is a creation of microdispersive powders calcium of М- type hexagonal ferrite using low-and high-temperature technology processes. Methods of researches: compexon-metric titration of inorganic ions, IR-spectroscopy, low-and high-temperature differential thermal analysis, electronic microscopy, X-ray analysis, the microanalysis of element composition, magnetometric measurements of output magnetic parameters. For the first time the complex approach to obtaining of high-dispersive multipurpose calcium hexaferrite is offered. This includes application of elements of cryochemical technology, introduction of the modifying additives stabilizing crystal structure, and addition of a low-melting flux. All these have allowed to create conditions for synthesis of the isolated microcrystals with size which do not exceed a singledomain limit. Synthesized high-disperse powders are intended for creation magnetizing medium and working medium for memory devices, for pharmacological and other medical applications.
