The ion-exchange procedure is used for doping the Ba-hexacelsian structure with Ca2+ and Pb2+ cations. The hexacelsian doped with Ca2+ has a composition of Ba0.64Ca0.36Al2Si2O8, and hexacelsian doped with Pb2+ has a composition Ba0.9Pb0.1Al2Si2O8. The crystal structure of both doped hexacelsians was refined by Rietveld refinement procedure. The crystal structure of Ca-hexacelsian is refined in the space group P (3) over bar c1, and results indicate ordering distribution of Si and Al (unit cell parameters is a = 5.2995, c = 15.594 angstrom and agreement factors: R-exp = 15.3 R-p = 19.9, R-wp = 19.0, R-B = 15.0 R-F = 4.08). Structural model for Pb-hexacelsian samples is described in the space group P6(3)/mcm with disorder distribution Si/Al (unit cell parameter is a = 5.2973, c = 15.591 angstrom and agreement factors R-exp = 21.5 R-p = 21.5, R-wp = 19.0, R-B = 5.74 R-F = 4.08). The results of Rietveld refinements indicate that Ca2+ and Pb2+ cations are incorporated into hexacelsian struc...ture in different position.
