The crystal structure of the Ba-Hexacelsian phases doped with Ca2+ and Pb2+
Abstract
The ion-exchange procedure is used for doping
the Ba-hexacelsian structure with Ca 2+ and Pb 2+ cations.
The hexacelsian doped with Ca 2+ has a composition of
Ba 0.64 Ca 0.36 Al 2 Si 2 O 8, and hexacelsian doped with Pb 2+
has a composition Ba 0.9 Pb 0.1 Al 2 Si 2 O8 . The crystal structure
of both doped hexacelsians was refined by Rietveld
refinement procedure. The crystal structure of Ca-hexac-
elsian is refined in the space group P 3c1, and results
indicate ordering distribution of Si and Al (unit cell
parameters is a = 5.2995, c = 15.594 A˚ and agreement
factors: Rexp = 15.3 Rp = 19.9, Rwp = 19.0, RB = 15.0
RF = 4.08). Structural model for Pb-hexacelsian samples is
described in the space group P6 3/mcm with disorder dis-
tribution Si/Al (unit cell parameter is a = 5.2973,
c = 15.591 A˚ and agreement factors Rexp = 21.5 Rp = 21.5,
Rwp = 19.0, RB = 5.74 RF = 4.08). The results of Rietveld
refinements indicate that Ca 2+ and Pb 2+ cations are
incorporated into hexacel...sian structure in different
position.
