Popis:	Subsolidus phase formation in the Ag3VO4-ScVO4 quasi-binary system was studied using X-ray powder diffraction and DTA in air under atmospheric pressure over the entire range of component concentrations in 5 mol % steps between 20 and 800°C. Two compounds were found to form: Ag3Sc(VO4)2 and Ag3Sc2(VO4)3, both melting incongruently at 750 ± 5 and 960 ± 5°C, respectively. A T-x diagram of the Ag3VO4-ScVO4 quasi-binary system was constructed. A eutectic (Tm = 450 ± 5°C) is between the compounds Ag3VO4 and Ag3Sc(VO4)2; Ag3VO4 concentration is ∼5 mol %.
