Symmetry-controlled routes (based on known and hypothetical crystal structures) for transforming the solid reactant into the solid product were devised as possible decomposition pathways. Lattice energies of the reactants, of the postulated transient intermediate structures and of the final solid products were then estimated by crystal modelling procedures. Profiles of lattice energy changes during the proposed decomposition routes were constructed and any energy barriers were compared with experimental activation energies reported for the thermal decompositions. The crystal modelling was performed with the computer program WMIN. Calculation of the lattice energies involved the development of a model potential for the perfect lattice and the evaluation of the interatomic parameters. The potential was based on the Born model of ionic solids using the Buckingham potential (Ø(r)= Ae⁻r/p - C/r⁶) to describe the short-range energy contribution. Empirical fitting was used to establish reliable interatomic energy parameters. The reliability of the interatomic potentials was assessed by calculating crystal structures and lattice energies (which were not included in the fitting). The particular reactions selected for modelling were the decompositions of the alkaline-earth metal (Ca, Sr, Ba) peroxides and carbonates: M0₂(s) ---> MO(s) + ¹/₂0₂(g) MC0₃(s) ---> MO(s) + CO₂(g)The lattice energies calculated for the known structures were in good agreement with reported values, (except for Ba0₂ and BaC0₃) which provided support for the adequacy of the potential model used. Activation energies calculated for the decomposition of the carbonates were in the correct order but hlgher than experimental values, i. e., 422, 422, 465 and 499 kJ mol̄̄⁻¹ compared to the experimental values of 205, 87(?), 222 and 283 kJ mol̄̄⁻¹ for CaC0₃ (calcite), CaC0₃(aragonite), SrC0₃ and BaC0₃. The values calculated for the peroxides (91 and 100 kJ mol⁻¹ compared to the experimental values of 119 and 185 kJ mol⁻¹ for Sr0₂ and Ba0₂ respectively) were less satisfactory but could be a reflection of the poor structural data used for the peroxides. The significance of this approach to the modelling of solid decompositions is discussed.]]> Wed 12 May 2021 16:15:12 SAST ]]> 6th National Congress Resolutions https://vital.seals.ac.za/vital/access/manager/Repository/vital:34298 Wed 12 May 2021 16:10:33 SAST ]]> Economic incentives in controlling pollution in the South African leather industry https://vital.seals.ac.za/vital/access/manager/Repository/vital:1010 Wed 12 May 2021 16:08:12 SAST ]]> Arbor day 005 (Picture 3) Don Maclennan https://vital.seals.ac.za/vital/access/manager/Repository/vital:26112 Wed 12 May 2021 16:05:55 SAST ]]> Fifty years of ichthyology in Grahamstown https://vital.seals.ac.za/vital/access/manager/Repository/vital:7138 Wed 12 May 2021 16:04:10 SAST ]]> A review of estuarine ichthyology in South Africa over the past 50 years https://vital.seals.ac.za/vital/access/manager/Repository/vital:7155 Wed 12 May 2021 15:52:37 SAST ]]> 6th National Congress Resolutions https://vital.seals.ac.za/vital/access/manager/Repository/vital:39284 Wed 12 May 2021 15:48:58 SAST ]]> Education service - Improving union organisation https://vital.seals.ac.za/vital/access/manager/Repository/vital:39893 Wed 12 May 2021 14:15:51 SAST ]]> 6th National Congress Resolutions https://vital.seals.ac.za/vital/access/manager/Repository/vital:42401 Wed 12 May 2021 14:07:17 SAST ]]> A programme for the alliance https://vital.seals.ac.za/vital/access/manager/Repository/vital:39902 Wed 12 May 2021 13:49:29 SAST ]]> Alkaline rocks in the Kuboos-Bremen Igneous Province, southern Namibia: the Grootpenseiland and Marinkas Kwela Complexes https://vital.seals.ac.za/vital/access/manager/Repository/vital:38471 Tue 18 Jul 2023 22:34:02 SAST ]]> Electrocatalytic oxidation of cysteine by molybdenum (V) phthalocyanine complexes https://vital.seals.ac.za/vital/access/manager/Repository/vital:57079 Thu 29 Sep 2022 22:16:40 SAST ]]> Cyclic voltammetry and spectroelectrochemistry of osmium phthalocyanines in aqueous and non-aqueous solvents https://vital.seals.ac.za/vital/access/manager/Repository/vital:57078 Thu 29 Sep 2022 22:14:14 SAST ]]> Conrad's impressionism : the treatment of space and atmosphere in selected works https://vital.seals.ac.za/vital/access/manager/Repository/vital:2229 Thu 14 Jul 2022 11:22:31 SAST ]]> Establishing criteria to evaluate reading programmes intended for intermediate to advanced level ESL learners in South African schools https://vital.seals.ac.za/vital/access/manager/Repository/vital:1521 Thu 13 May 2021 08:48:45 SAST ]]> Geochemical stratigraphy of the Mohale Dame-Katse Dam areas, Lesotho.
