  The paper presents the investigation of ordinary and ternary vanadates with
zircon and monazite structures. Vanadates LnVO4 and CaLnZr(VO4)3 , where (Ln =
La, Nd, Sm, Eu, Gd, Dy, Yb) and solid solution La0.3Nd0.5Sm0.1Eu0.1VO4, were
prepared by precipitation reaction. Bulk ceramic samples were obtained from
powders by Spark Plasma Sintering (SPS). The powders and ceramics were examined
with several physicochemical methods. The coefficients of thermal expansion at
900{\deg}C were determined. The hydrolytic stability of ceramic materials was
studied. The peculiarities of high-rate SPS of powders of ordinary and ternary
vanadates were analyzed.
