HEIGH-FREQUENCY-THERMAL ANALYSIS

Abstract

The object of investigation: the oxide, salt, water-salt, organic, water-organic systems. The purpose of the work: the development of the new method of the investigations - the high-frequency-thermal analysis. The equipment, recording simultaneously the thermal effects of the conversions and the processes of ordering-disordered the structures of solid phases in the dynamic, has been created. The theory of the high-frequency-thermal analysis has been developed; the qualitatively new information about the phase and chemical transformations has been obtained. The phase transformations not accompanying with disordering of the structure, skin-effect in the electrolyte systems, the solid solution of the water microquantities in the ion crystals, not rnown earlier, the sequential activation of the solid phases with the solid-phase reactions, the reasons of existing of the characteristic temperatures and the deviattions from the Headwall's rule have been detected. The small-series manufacture of the equipment has been realized. The fields of application: the chemistry of the solid body, the physico-chemical analysis, the material-keeping.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
