摘要：

Four (Zn1-xMgx)3(PO4)2 solid solutions have been prepared at 800°C and the crystal structures (P21n; Z = 2) refined with the Rietveld technique on the basis of X-ray powder diffractometer data. The structure factor R-values are in the region 0.03-0.08 for 274 independent reflections. The Zn+2/Mg+2 cation distribution is ordered with zinc preferably at the five-coordinated and magnesium at the six-coordinated metal sites. The cation distribution coefficient KD is around 20 irrespective of the composition. © 1992 Academic Press, Inc.
