Abstract:The extraction of metal from sulfide mineral is usually accompanied by the emission of sulfur-containing gas (e.g., SO 2 ), which will cause serious pollution to the environment. In this work, a sulfur-emission free route for preparing ultrafine molybdenum disilicide (MoSi 2 ) powder by silicothermic reduction of MoS 2 with the desulfurization agent of lime was proposed. The internal MoS 2 -Si mixture is wrapped in an external desulfurization layer composed of lime. After the reaction is completed, the prepare… Show more
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.
