Metallic titanium and rutile (rutile particle size 25 μm, specific surface area 3 m2/g) were used as starting materials for the synthesis of titanium salts, which were subsequently decomposed. Titanium salts were obtained by interaction with mineral acids and ammonium carbonate. The obtained salts were thermally decomposed or hydrolyzed by the addition of ammonium hydroxide, which resulted in the precipitation of titanium oxide. The phase composition of the synthesized samples included rutile and anatase, as well as impurities of titanium fluoride observed at low firing temperatures. A relatively simple and economically feasible method for the synthesis of titanium oxide with specific surface area up to 92 m2/g has been proposed. This method involves simple chemical transformations, which include thermal decomposition of synthesized titanium halides. The best of the synthesized anatase samples had the shape of irregular polyps, specific surface from 56 – 92 m2/g, and particle size in the range of 20 – 60 μm.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"81 11-12","pages":"464 - 470"},"PeriodicalIF":0.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Model tests are used to evaluate the compliance of algorithms with technical specifications and their reliability. The tests were carried out on a test bench built on the basis of an industrial sample. On the test bench the operation of the object is modeled, parameters are recorded and transferred to the monitoring system for post-processing. In the course of testing, the component base of various manufacturers available under the sanctions policy was tested. It was confirmed that such a stand can be used for rapid prototyping of control algorithms, semi-natural testing, and training of glass industry specialists. The independent control of the process control system is a contributing factor to the development of industrial equipment engineering and the localization of critical technologies. Consequently, this contributes to the formation of technological sovereignty.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"81 11-12","pages":"513 - 520"},"PeriodicalIF":0.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The materials were characterized using x-ray diffraction (XRD), infrared (IR) spectroscopy, low-temperature nitrogen adsorption/desorption, scanning electron microscopy (SEM), electrophoretic light scattering, and energy-dispersive spectroscopy (EDS). The duration of hydrothermal treatment significantly influenced the crystallite size of titanium dioxide and the anatase-to-rutile phase ratio, as well as the surface morphology and textural properties of the composites. Photometric analysis was used to evaluate the adsorption capacity and photocatalytic activity of the composites toward Rhodamine B as a model dye. Overall, hydrothermal treatment substantially enhanced the photocatalytic activity of the composites. However, prolonged treatment duration resulted in a decline in this effect. The obtained composites exhibited a pronounced synergistic effect of adsorption and photocatalysis in removing Rhodamine B from a highly concentrated (40 mg/L) aqueous solution.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"81 11-12","pages":"457 - 463"},"PeriodicalIF":0.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The regularities occurring at the stage of mechanochemical activation and sucsequent thermal treatment were investigated by means of x-ray diffraction (XRD) and synchronous thermal analysis methods. The influence of the energy intensity of the mill on the textural properties of the composite was demonstrated. Low-temperature nitrogen adsorption-desorption showed that in the process of mechanochemical synthesis the total specific surface area of the samples changes insignificantly, while the type of processing has a significant effect on textural properties including pore size distribution, active surface area, and copper dispersion. Temperature ranges of composite activation for catalytic applications were obtained by the method of thermo-programmed reduction. The positive influence of the mechanical activation on the formation of the composite structure was observed. This allows its use as the main component of the catalyst for the production of ammonia, hydrogen, and methanol.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"81 11-12","pages":"471 - 476"},"PeriodicalIF":0.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clay agglomerates were predominantly up to 10 – 20 microns in size. X-ray spectral analysis revealed a relatively high content of Fe2O3, Na2O, CaO, which corresponds to the iron-aluminum variant of montmorillonite with a predominance of Na+ and Ca2+ ions in the interlayer space. The presence of potassium indicates the presence of illite. According to XRD data, the main component of the product is montmorillonite with impurities of quartz/cristobalite, kaolinite, illite, and hematite. Thermal analysis curves and IR spectrum of bentonite were analyzed. The textural characteristics of the powder were determined. The specific surface area was 58 ± 6 m2/g. Based on bentonite and orthophosphoric acid, a geopolymer bentonite-phosphate binder was synthesized for the first time. XRD and IR spectral analysis show that the interaction of aluminosilicate powder with orthophosphoric acid leads to the complete destruction of the montmorillonite structure with the formation of aluminum and silicon phosphates.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"81 11-12","pages":"477 - 481"},"PeriodicalIF":0.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
