Thanks to the successful stages of research, significant results were obtained with the determination of temperature conditions that increase the probability of reactions to the formation of carbides and elements in the Free State during reduction with both carbon and CO and carbides. From a thermo- dynamic point of view, higher oxide compounds have a lower strength than lower oxides. In the studied system, reactions of formation of metal oxides and carbides, metals in the Free State, as well as CO and CO 2 are likely. The tendency of oxide compounds of refractory metals to reduction with the participation of C, CO and carbides is determined. A high probability of parallel carbide formation reactions along with reduction at relatively low temperatures is determined. As the temperature increases, the probability of reduction to metals in the Free State increases. At the same time, the role of carbides as reducing agents increases with increasing temperature. A higher probability of reduction reactions of higher oxides than lower ones is determined. At the same time, the production of a reduced product without carbides is unlikely. Taking into account phase transitions and changes in the heat capacity of reaction components with increasing temperature made it possible to obtain more accurate results. The significant number of reactions considered over a wide temperature range highlights a more complete picture of possible transformations in the process of recovery of doped technogenic waste. Simultaneously with the restoration and return to production of man-made metallurgical waste, it is implemented to reduce environmental pollution and reduce environmental tension in regions with developed industry, which in turn leads to an increase in life safety.","PeriodicalId":33778,"journal":{"name":"Metall i lit''e Ukrainy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44595398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
