Abstract

The Double Phosphates M I M II PO4 (M I : Na, K; M II : Mg, Mn, Co, Ni, Zn) -Synthesis from Chloride Melts and Characterization. -Interactions in the systems M I PO3-M II O (or Mn2O3)-M I Cl (M I : Na, K; M II : Mg, Co, Ni, Zn) are investigated at molar ratios P/M x = 1 or 2, and M I Cl/(M I PO3 + M II O) = 30 (porcelain crucibles, 1073 K, 3-5 h). The samples are characterized by powder XRD, FTIR spectroscopy, and UV/VIS diffuse reflectance spectroscopy. The main advantages of the synthesis of the title compounds from chloride melts are synthesis time reduction, reduced reaction temperature, and the possibility of crystal size control. -(LIVITSKA*, O.

“…This peaks complicated structure is linked to the spin-orbit interaction, which is common in cobalt-containing compounds. 41 A plot of (ahn) 1/2 versus photon energy (hn) can be used to determine the indirect band gap energy. As a result, Fig.…”
