Abstract

The results of the study of the physicochemical properties of the modified saponite isolated from the recycled water of the enrichment plant of Severalmaz JSC showed that the process of intercalation of cations of different nature into its structure changes the electrical conductivity of the samples, which makes it possible to control the residual moisture content of the material. In addition, changing the nature of the cations introduced into the interpackage distance of the saponite makes it possible to minimize the firing shrinkage of the raw saponite in the manufacture of ceramic products. Singly charged (\({\text{NH}}_{4}^{ + },\) Na⁺), doubly charged (Mg²⁺, Ca²⁺), and triply charged (Fe³⁺) ions were used as intercalated cations. It has been established that the electrical resistance for all the studied samples increases according to a power function as moisture is removed, and the shrinkage of the saponite-containing raw material, depending on the introduced cation, can be reduced by 30 to 40%.

不同阳离子性质电解质溶液中皂土的插层

对从Severalmaz JSC富集厂循化水中分离得到的改性皂土的理化性质研究结果表明，不同性质阳离子插入其结构的过程改变了样品的电导率，从而使控制材料的残余水分含量成为可能。此外，改变引入皂土包间距离的阳离子的性质，可以最大限度地减少原料皂土在陶瓷产品制造中的烧成收缩。单电荷（\({\text{NH}}_{4}^{ + },\) Na+），双电荷（Mg2+, Ca2+）和三电荷（Fe3+）离子被用作插层阳离子。已经确定，随着水分的去除，所有研究样品的电阻都按幂函数增加，并且根据引入阳离子的不同，含皂石原料的收缩率可以降低30 - 40％%.

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
