文摘

The well-ordered NASICON-type Mg²⁺ conductor (Mg_xHf_1-x)_4/(4-2x)Nb (PO₄)₃ is obtained by partial substitution of lower valent Mg²⁺ for Hf⁴⁺ in HfNb(PO₄)₃ via co-precipitation from EtOH solutions of Mg(NO₃)₂, HfCl₄, and NbCl₅ to which (NH₄)₂HPO₄ is given (130 °C, 1 d) followed by staged calcination in air (600—1300 °C, 6 h per stage with intermediate grinding).
