Mixed orthophosphates (Na/sub 3/Ln/sub x/(PO/sub 4/)/sub y/) containing sodium and lanthanide elements have been prepared by several synthetic methods and have been characterized by Raman spectroscopy at both ambient and elevated temperatures, X-ray diffraction, and neutron activation analysis. The elements from La to Gd have been observed to form compounds with the stoichiometry Na/sub 3/Ln(PO/sub 4/)/sub 2/, which exhibit only one type of symmetry. Yttrium and the elements from Tb to Lu form compounds with the stoichiometries Na/sub 3/Ln(PO/sub 4/)/sub 2/ and Na/sub 3/Ln/sub 2/(PO/sub 4/)/sub 3/. Each compound occurs in several crystal symmetries. One of these, designated as phase ..gamma.., appears to be a new phase. 16 references, 5 figures, 4 tables.
