Abstract

<abstract abstract-type="graphical" xml:lang="en" id="crat201500050-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The crystallization of molten system Rb₂O‐P₂O₅‐TiO‐NiO was investigated at molar ratios Rb/P=0.5‐1.3, Ti/P=0.15, Ti/Ni=1.0. The phosphates RbTi₂(PO₄)₃, Rb₂Ni_0.5Ti_1.5(PO₄)₃ and RbNiPO₄ have been prepared and characterized. The new obtained phosphate Rb₂Ni_0.5Ti_1.5(PO₄)₃ belongs to the langbeinite family (cubic system, space group P2₁3, a = 9.9386(2)Å). Three‐dimensional framework of Rb₂Ni_0.5Ti_1.5(PO₄)₃ is build up from mixed (Ni/Ti)O₆‐octahedra and PO₄‐tetrahedra. Rb cations are located in the closed cavities of the framework. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj1z9dvnwx" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
