Modeling with the use of data for bounding systems is important for constructing phase diagrams of ternary and multicomponent systems. Using three-dimensional vector graphics software, we have constructed a 3D model of equilibrium phase states in the pseudoternary system LiF–NaF–KBr, which is a stable composition triangle in the quaternary reciprocal system Li+,Na+,K+||F–,Br–. Based on the 3D model, we have constructed for the first time polythermal and crystallization polytherm. For two polythermal sections, we have demonstrated the presence of regions of limited sodium fluoride-based solid solutions and liquid miscibility gaps and identified the phase crystallization sequence. In the 620°C isothermal section, we have delineated liquid-phase and two- and three-phase fields. The polytherm comprises three crystallization fields: terminal solid solutions based on sodium fluoride, potassium bromide, and lithium fluoride, in which a liquid miscibility gap has been delineated. The stability of the LiF–NaF–KBr composition triangle has been confirmed by thermodynamic calculations for several temperatures of interaction in mixtures of substances in the unstable composition triangle LiBr–NaF–KF. The crystallization polytherm allows one to choose mixtures in the temperature ranges 625–650 and 625–700°C suitable for practical application as melting electrolytes of intermediate-temperature electrochemical cells and molten solvents of inorganic substances.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"60 9","pages":"1101 - 1108"},"PeriodicalIF":0.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645387","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}

Using a high-energy planetary ball mill, the mineral mixture was ground into fine powder. We have studied the process of dispersing the mineral components of the mixture in relation to the main process parameters: vial rotation speed, ball-to-powder weight ratio, and milling time. The results demonstrate that, under “severe” grinding conditions, disintegration of brittle particles of the minerals sphene and aegirine slows down owing to the plasticity of the particles of the minerals apatite and nepheline, which reduces the efficiency of the high-energy grinding process, aimed at reducing the particle size and increasing the specific surface area of the material. The grinding process has been shown to cause not only a reduction in the size of mineral particles, but also changes in their optical properties through amorphization of their surface. This allows mechanically activated powder to be used as a precursor for the preparation of weather-resistant color filler pigments for building and paint materials instead of expensive synthetic analogs.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"60 11","pages":"1380 - 1390"},"PeriodicalIF":0.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645629","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}
