Size and Charge Effects of Dopant M on the Unit-Cell Parameters of Monoclinic Zirconia Solid Solutions Zr0.98M0.02O2 – (M = Ce, La, Nd, Sm, Y, Er, Yb, Sc, Mg, Ca)
Abstract:The crystal structure of monoclinic phase [P21/cZ= 4] has been refined by the Rietveld analysis of X-ray powder diffraction data to study the size and charge effects of dopant Mn+ on the unit-cell parameters of monoclinic ZrO2−2 mol% MOn/2 solid solutions (n= 4 for M = Ce; n= 3 for M = La, Nd, Sm, Y, Er, Yb, Sc; and n= 2 for M = Mg and Ca). For trivalent dopant (n= 3), the unit-cell parameters am, bm, cm and unit-cell volume increase and m decreases with an increase of dopant size. Unit-cell volume increases with increasing of dopant charge n.
