Contribution a l'etude des systemes Ca3(PO4)2-MSO4 (M=Sr, Ba)

Abstract

In the systems Ca3(PO4)2-MSO4 (M = Sr, Ba), the series of single phase Cael-3xMzx(PO4)14--2x(SO4)2x with 0<x<0.15 for M = Sr and 0<x<0.1 for M = Ba have been prepared. These solid solutions, respectively strontium phosphosulfate and barium phosphosulfate, are isostructural with anhydrous tricalcium orthophosphate. They have been characterized by their infrared spectra and their crystallographic unit cell parameters.
