Abstract

The phases of variable composition Ca3 − 3x Nd2x (AO4)2 (A = P, V; 0 ≤ x ≤ 0.14) based on calcium orthophosphate or orthovanadate are studied by Raman spectroscopy. The influence of the composition and temperature on the structural features of these compounds is considered. The changes observed in the Raman spectra at high temperatures are associated with the reversible phase transition due to the redistribution of calcium over different positions and partial reorientation of the AO4 tetrahedra.
