The crystal structure of monoclinic phase [ P 2 1 / 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 M n + on the unit‐cell parameters of monoclinic ZrO 2 −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 .
