Phase transitions during compression of thaumasite, $ Ca_{3} $Si(OH)6($ CO_{3} $)($ SO_{4} $)·$ 12H_{2} $O: A high-pressure synchrotron powder X-ray diffraction study
Abstract The high-pressure behaviour of the thaumasite structure was investigated using synchrotron powder X-ray diffraction, up to 19.5 GPa. Based on Rietveld refinements, thaumasite retained the roompressure $ P6_{3} $ space group throughout the whole investigated pressure range while the pressure...

520 | |a Abstract The high-pressure behaviour of the thaumasite structure was investigated using synchrotron powder X-ray diffraction, up to 19.5 GPa. Based on Rietveld refinements, thaumasite retained the roompressure $ P6_{3} $ space group throughout the whole investigated pressure range while the pressure dependence of the refined unit-cell parameters can be cast into three different compression regimes, each corresponding to a different thaumasite phase (th-I, th-II and th-III) related by isosymmetric phase transitions. In particular, the phase transition in the 7.40-15.02 GPa P-range (i.e. from th-II to th-III) is associated with an inversion of the axial bulk moduli which, by analogy with ettringite, can be rationalized as due to a change in the relative strengths of the iono-covalent bonds along the [$ Ca_{3} $Si(OH)6($ H_{2} $O)12]4+ columns parallel to the c axis vs. the O-H bonds linking the columns within the ab plane. The linear inverse relationship between the low- and high-temperature data from the literature with those collected under high-pressure conditions reveals that the same bonding regime governs the anisotropic expansion and contraction of thaumasite up to ~1.4 GPa and 400 K (HP-HT stability limits of th-I phase). | ||

In particular, the phase transition in the 7.40-15.02 GPa P-range (i.e. from th-II to th-III) is associated with an inversion of the axial bulk moduli which, by analogy with ettringite, can be rationalized as due to a change in the relative strengths of the iono-covalent bonds along the [$ Ca_{3} $Si(OH)6($ H_{2} $O)12]4+ columns parallel to the c axis vs. the O-H bonds linking the columns within the ab plane. The linear inverse relationship between the low- and high-temperature data from the literature with those collected under high-pressure conditions reveals that the same bonding regime governs the anisotropic expansion and contraction of thaumasite up to ~1.4 GPa and 400 K (HP-HT stability limits of th-I phase).</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cruciani, G.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dondi, M.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Garbarino, G.

Phase transitions during compression of thaumasite, $ Ca_{3} $Si(OH)6($ CO_{3} $)($ SO_{4} $)·$ 12H_{2} $O: A high-pressure synchrotron powder X-ray diffraction study |
abstract |
Abstract The high-pressure behaviour of the thaumasite structure was investigated using synchrotron powder X-ray diffraction, up to 19.5 GPa. Based on Rietveld refinements, thaumasite retained the roompressure $ P6_{3} $ space group throughout the whole investigated pressure range while the pressure dependence of the refined unit-cell parameters can be cast into three different compression regimes, each corresponding to a different thaumasite phase (th-I, th-II and th-III) related by isosymmetric phase transitions. In particular, the phase transition in the 7.40-15.02 GPa P-range (i.e. from th-II to th-III) is associated with an inversion of the axial bulk moduli which, by analogy with ettringite, can be rationalized as due to a change in the relative strengths of the iono-covalent bonds along the [$ Ca_{3} $Si(OH)6($ H_{2} $O)12]4+ columns parallel to the c axis vs. the O-H bonds linking the columns within the ab plane. The linear inverse relationship between the low- and high-temperature data from the literature with those collected under high-pressure conditions reveals that the same bonding regime governs the anisotropic expansion and contraction of thaumasite up to ~1.4 GPa and 400 K (HP-HT stability limits of th-I phase). © 2015 by Walter de Gruyter Berlin/Boston |
