The crystal structure of defect KBB’O6 pyrochlores (B,B’: Nb,W,Sb,Te) revisited from neutron diffraction data
(MDPI AG, 2018-10-20)
Three defect pyrochlores KNbWO6·xH2O, KNbTeO6 and KSbWO6 were synthesized by solid state reaction at 750 °C, from stoichiometric mixtures of K2C2O4, Sb2O3, Nb2O5, WO3 and 20% excess TeO2. A neutron powder diffraction (NPD) ...
