Abstract
We have studied tetragonal scheelite-like solid solutions in the ternary system Na2MoO4-CaMoO4-Ce2/3MoO4: Na 0.7Cay Ce1.1 − 2y/3 (MoO4)2 (0 ≤ y ≤ 0.6) and Na0.3 CazCe1.23− 2z/3 (MoO4)2 (0 ≤ z ≤ 1.4). The solid solutions melt congruently at temperatures from 1100 to 1200°C. Their lattice parameters have been determined. Using reflection spectra, we evaluated the color parameters of all the samples studied.
