Structural Aspect of Glass Formation in Aqueous Electrolyte Glass-Forming Systems

Resumo

Water–electrolyte systems containing aqueous solutions of Group I–III metal, transition metal, and lanthanide nitrates, iodates, sulfates, acetates, orthophosphates, chlorides, and fluorides, inorganic acids, as well as aqueous and nonaqueous solutions of some of organic compounds (alcohols, acids, aromatic hydrocarbons) have been studied. The research methodology developed at the Institute of General and Inorganic Chemistry, RAS, and the analysis of experimental data have no analogues in our country and abroad. On the basis of the results obtained, general tendencies of glass formation in various water–electrolyte systems have been revealed. For the first time, a polymeric structure of glass-forming compositions of a number of water–electrolyte systems has been proved. The assumption is made that the nature of glass formation in water–electrolyte systems is the same as in systems containing “classical glass” (phosphates, silicates, and others) and organic glass-forming systems, that is, polymeric nature.
