Abstract:

This report discusses ten compounds which are potential host materials for quadruply ionized elements with 4dn and 5dn electronic configurations. These compounds are ZrSiO4HfGeO4Li2ZrTeO6Li2HfTeO6Li6BeZrF12ZrGeO4,ZrGeO8ThSiO4 and ThGeO4 in two forms zircon and scheelite. The crystal-field components, Anm are calculated for the Zr, Hf, and Th sites in each of the compounds. The site symmetry is S4 or D2d except for Li2XTeO6XZr, Hf which has C3 symmetry. Approximate parameters, Fk, BnmB, C, Dq, are given for the entire quadruply ionized 5dN configuration.
