Abstract

The crystal structure of monoclinic phase [P2₁/c, Z = 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% MO_n/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 a_m, b_m, c_m and unit-cell volume increase and β_m decreases with an increase of dopant size. Unit-cell volume increases with increasing of dopant charge n.
