A simple and green route for the preparation of CaV 2 O 4 through one-step incomplete electrochemical reduction of soluble NaVO 3 in CaCl 2 molten salt is proposed. NaVO 3 was found to exist in the form of Ca 2 VO 4 Cl in the molten salt with VO 4 3− as the reactive ion. CaV 2 O 4 possessing a surface carbon layer and rod structure was obtained by adding CaCO 3 during electrolysis. The electrochemical reduction mechanism was also analyzed, and the results indicated that VO 4 3− was incompletely reduced to VO 2 − at about −1.23 V (vs. Ag/AgCl) by a two-electron transfer process. VO 2 − ions then combined with Ca 2+ to form CaV 2 O 4 . Meanwhile, CO 3 2− was reduced to carbon in a two-step process.

“…The halophosphates were formed by firing appropriate mixtures of Yb203, MHPO4 (M -----Ca, Sr, Ba) and the corresponding halide MC12 in hydrogen (9). Similarly, the calcium halovanadate was prepared by firing the appropriate mixture of Yb2Oa, V205, CaCO3, and CaCI~ in air, as described by Banks et al (10). The halide is added in excess for fluxing purposes.…”

The luminescence of Yb2+ in alkaline earth phosphates and vanadates is reported. Particular attention has been given to those compositions possessing apatite and spodiosite structures. Emissions from Yb2+ are broad and sensitive to host composition. Single and double emission bands are observed which exhibit a variety of temperature dependent relationships. The decay of the Yb2+ fluorescence, under cathode‐ray excitation, is short.

The compound Pb 2 PO 4 I was synthesized via a solid state reaction under inert conditions. None of the known structure types of other compounds of the type M 2 (P,V,As,Cr)O 4 (F,Cl,Br,I) provided a similar pattern. Structure solution was carried out by evaluation of an X-ray diffractogram of polycrystalline powder using the methods simulated annealing and difference Fourier. Pb 2 PO 4 I crystallizes in the * Dr. R. Haberkorn 3153 space group P2 1 /c with the lattice parameters a = 9.0451(1) Å, b = 8.7593(1) Å, c = 8.5740(1) Å, and β = 111.128(1)°. The isotypic compounds Sr 2 PO 4 I and Ba 2 PO 4 I were synthesized, too. Their crystallographic structure was refined by Rietveld analysis. The structure of the three compounds is described and discussed.

New analogs of spodiosite, Ca2VO4Cl and Ca2AsO4Cl

Abstract: are evident indicating a removal of the degeneracy of the 3E state. This is possibly the result of spin-orbit coupling or a loss of Ds symmetry through ion pairing.
