A new environmentally friendly (no waste gas, liquid, and slag), efficient (two steps), and low-cost (wastes as raw material) approach is proposed to recycle spent SCR catalysts and Al alloy scrap for preparing TiAl3 and low-Fe Al alloys.
The large amounts of accumulated titanium (Ti)-bearing blast furnace slag are not only an industrial waste but also an important Ti resource. TiSi2 is widely used in high-tech industries and...
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.
