Solid-State Metathetic Synthesis of Phase Pure BaSnO3 and BaZrO3

U. Sujana Kumari, P. Suresh & A. A. V. Prasada Rao · International Research Journal of Pure and Applied Chemistry · 2013

A simple solid state metathetic  synthesis has been developed for the preparation of BaSnO3 and BaZrO3 making use of BaCl2 along with Na2SnO3 and K2[ZrO(C2O4)2].3H2O as precursors. Phase pure compounds in each case were obtained at lower temperatures than those reported in litera...

Grinding-Assisted Solid-State Metathetic Synthesis of Divalent Transition Metal Tungstates

U. Sujana Kumari, P. Suresh & A. V. Prasada Rao · International Research Journal of Pure and Applied Chemistry · 2013

A convenient solid state metathetic synthesis has been developed for the preparation of metal tungstates MWO4 where M = Mn, Fe, Co, Ni and Zn using Na2WO4 and respective MCl2 as reactants. Stoichiometric quantities of respective reactants were mixed and ground for 2hrs. XRD patte...
