WebbThese trends are opposite to that expected based on ionic-radii and tolerance factor arguments. This anomalous behavior is attributed to an ion-size mismatch (cation variance) effect on the A-site between the Ba2+ and Gd3+ ions that induces local strain in the lattice that suppresses the reduction in the c/a ratio and cell volume, and as a … WebbThe ionic radii proposed by SHANNON and PREWITT as the effective values in oxides and fluorides have been analysed for their conformity with the radius ratio principles of crystal chemistry. It is shown that a set of values intermediate between the "IR" and "CR" values of SHANNON and PREWITT provides the best conformity in this respect, and a table of the …
