Crystal structure parameters have been determined for a compositionally intermediate scapolite (Na, nrCa,.rrK' ro) (Si8.0sAl3 e5)Or4Cl' u"(COr)0.(SOr)o on in space group P4r/nbefore and after a heating cycle. In addition, unit-cell parameters have been determined with roomtemperature data col lected before and after heating, and with data col lected at 400… (More)
