Hydrogen-stabilized alkaline earth metal pnictides, Ae{sub 5}Pn{sub 3}
- Iowa State Univ., Ames, IA (United States)
The majority of the Ae{sub 5}Pn{sub 3} phases (Ae = Ca, Sr, Ba, Pn = Sb, Bi) with the Mn{sub 5}Si{sub 3} structure tend to bind a third element interstitially, Ae{sub 5}Pn{sub 3}Z, while a second phase with the {beta}-Yb{sub 5}Sb{sub 3} structure has been observed for the {open_quotes}binaries{close_quotes} Ca{sub 5}Pn{sub 3} and Sr{sub 5}Bi{sub 3}. On the other hand, little or no attention has been given to the non-metallic impurities, e.g. hydrogen, present in the commercially available alkaline earth metals and their influence on the formation of intermetallic phases. Recent results on the work about the influence of hydrogen on the Ae{sub 5}Pn{sub 3} compounds indicate that, with the possible exception of Ca{sub 5}Bi{sub 3}, the phases with {beta}-Yb{sub 5}Sb{sub 3} structure are in reality hydrides. The phases with Mn{sub 5}Si{sub 3} structure can also be hydrides.
