The isovalent substitutions of Sr2+, Pr3+, (GeO4)4− and (VO4)3− in the respective cationic and anionic sites of Ca4La6(SiO4)4(PO4)2O2 have been accomplished. The substitution of Sr2+ for Ca2+ decreases εr and Qu × f but ...

Magnesium-substituted europium vanadate ceramics, MgxEuVO4 ± (x = 0–0.5), were prepared by solidstate method and characterized by XRD, SEM/EDS, dilatometry, UV–vis spectroscopy, impedance spec-troscopy, and measurements ...

A cost effective protocol to develop microwave substrate is proposed whereby a mixed rare earth orthophosphate [REMIXPO4] ceramic was prepared using a natural mixture of rare earth oxides, which is a byproduct derived from ...
