Abstract:Anewhigh-pressure phase of CrSb2 has been synthesized from the marcasite-type ambient pressure phase by high-pressure/ temperature treatment above 5.5 GPa. The crystal structure of the high-pressure phase is body-centered tetragonal, which is assigned as CuAIZ type structure. The bond nature in the high-pressure phase is metallic, in contrast to the mixed ionic and covalent character in the marcasite-type phase. The phase transition, marcasite-type to CuAIZ type, accompanies 11% volume decrease and a change of… 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.
