A distinctive feature of phosphates is their special and significant ability to form inorganic polymeric compounds---condensed phosphates, which are destined to play a considerable role in our "high-tech" society in the future. Numerous olygophosphates, polyphosphates, double condensed phosphates and cyclophosphates with diverse formula, such as double tetra-, octa- and dodecaphosphates were obtained and described by us last years. The offered data are the outcomes of our scientific researches: of synthesis, analysis, and estimation of results in correlation with new achievements in inorganic polymer's chemistry. Many double condensed compounds, containing monovalent metals are obtained by us during systematic investigation of polycomponent systems, containing mono- and trivalent metals at temperature range 100-600 ~C. Synthesised condensed phosphates, in fact--inorganic polymers were examined in detail by chemical and thermogravimetric analysis, most compounds were examined by paper chromatography and the structures are determined by X-ray structural techniques/diffraction analysis. During our fundamental researches numerous new (about 70) unknown until now condensed phosphates have been obtained. Dependency of composition VS temperature and molar ratio, reliance of structure from duration of synthesis and radius of the ions are revealed. 展开更多
