Intermediate compounds in SrB2O4 – SrREE2O4
Chimednorov Otgonbayar, Herbert Pöllmann
Strontium rare earth borates, Sr3REE2(BO3)4 (REE = Nd, Sm, Eu, Gd, Y and Yb), were synthesized as single phase powders starting from the respective oxides in the temperature range of 1000 °C and 1200 °C. These isostructural phases crystallise in the space group Pnma. The vibrational spectre confirms the presence of planar trigonal coordinated borates. Lattice parameters are refined by Pawley method.
