Objective - development of scientific bases of a new high-tech efficiency of processes RP modification of matrix materials to make them stable abnormally high RP properties and on this basis, the development of rare-earth samples of products new technical level. The method of investigation - laboratory testing, research and development of rational technological parameters: RP application of coatings on woven matrix, causing the RP covering the intermediate carrier in the form of granules keramzite; give high RH properties of the matrix on the basis of plaster knitting, weaving samples of rare-earth products of the new technical standards and radiation testing. As a result of the investigations found: By applying ultrasonic vibrations MHz frequency on a suspension of polydisperse granular RP modifier in the form of complex in the liquid phase of polydisperse modifier can effectively allocate an additional significant amount of UDP; justified by rational choice of solvents and the optimal concentration in norx RP modifier in the form of a polydisperse mixture of complex oxides before applying coatings RP; substantiated the main technological parameters to give high RP properties of the matrix based on gypsum binder, in particular, vodogipsovoe ratio, the concentration of modifierThe time ultrasound effects on suspension of complex in the liquid phase, and others, performed patent research to develop technologies to give the properties of various rare-earth matrix materials. The novelty of the work performed is based on a fundamentally new development in the area giving abnormally high RP properties of different matrix materials. Forecasting assumptions about the development of the object of research: the findings will be used in mastering the production of high-performance rare-earth products of new generation.
