“…В техно-логии силикатных материалов во многих про-цессах синтеза ГСК основной лимитирующий фактор -низкая химическая активность квар-цевого компонента. В [5,6] наглядно представ-лено позитивное влияние механоактивации на процессы взаимодействия кремнеземистого компонента с получением различных продук-тов. Замечено, что в большей степени механо-активации подвергаются твердые и хрупкие материалы с большой долей ковалентных свя-зей, в то время как пластические компоненты с идеальной спаянностью почти не поддаются активации такого рода.…”

“…The calcium hydrosilicates can also be used as raw materials for the wollastonite, which in turn can be used as filler for PVC-based composites. Such filler increases whiteness of composite [2]. Application of wollastonite can be recommended during synthesis of the carrier agents of liquid synthetic rubbers and synthesis of concentrates of solid silane agents [3].…”

“…It is advisable to synthesize the barium hydrosilicates by means of low-temperature technology [5]. However, for synthesis of these hydrosilicates is proposed to use the amount of hardener which is different from stochiometric (80, 95, 100, 110 ... 150% ) [1,2,6,7,8]. Obviously, the concentration factor has a significant influence on the chemical composition, structure and properties of the products of synthesis.…”

One of the promising directions of quality improvement of building materials (based on various binders) is to use hydrosilicates of calcium and barium. In particular, it is known that the application of calcium hydrosilicates can improve the compression strength in two or three times; the fracture toughness can be increased in two times and more. Prospects of using barium hydrosilicates in cement systems are due to the similarity of the chemical composition (with calcium hydrosilicates) and advantages of barium cements compared to traditional cements. It is advisable to synthesize the barium hydrosilicates by means of low-temperature technology. To investigate the influence of the curing agent (barium chloride) to the properties of the reaction products in the present study the IR spectroscopy and differential scanning calorimetry (DSC) are used. Analysis of the results allowed to state that the main reaction product is a crystalline silicate phase. Reducing the amount of curing agent leads to an increase of the content of silicic acid. DSC results show that dehydration of barium hydrosilicates takes place in two stages. It is typical for systems BaO•SiO2•6H2O. Increasing the content of silicic acid is accompanied by an endothermic effect in temperature range of 120...130 °C. Joint analysis of the results of IR spectroscopy and DSC leads to the conclusion that there is a reaction of barium carbonate and silicic acid. In general case, reduction of the amount of the curing agent contributes to increase of content of the silica acid and barium carbonate. Therefore, it is advisable to use compositions prepared with reduced amount of BaCl2 in systems capable of interacting with the silica acid and forming the insoluble products.
