Conditions for the reduction of titaniummagnetite concentrates (main components are Fe 52-54 % and TiO 2 5-7 %) by natural gas for obtaining iron powder and titanium fraction were studied. Based on the theory of granulation in the drum apparatus, granules with 25 % of soda fluxing additive with optimum diameter, humidity, strength and porosity were obtained. It was found that the reduction reactions in the temperature range of 1143-1198 K are carried out if a mixture of hydrogen and carbon monoxide is added to the natural gas in amount of 15 vol %. Block-diagrams for processing titaniummagnetite concentrates for the production of iron powder α-Fe (purity 99 %), anatase and rutile modifications of titanium dioxide (99 % TiO 2 ) and titanium with a purity of 99% are presented.
Information about methods of preparation, structure and physical-chemical properties of nanostructured materials based on lithium and sodium titanates was analyzed and summarized. The functional nanostructured composite materials based on sodium and lithium titanates to produce an anode material with high capacity and working stable potential in the course of cycling with optimal electronic and ionic conductivity were examined. Examples of specific schemes, physical-chemical properties and the mechanism of functional processes by using bioactive and doped components were presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
