Autor: Yanchao Wang, Yunwei Zhang, Yue Chen, Jian Lv, Yanming Ma, Weitao Zheng, Sheng Wang

Publikováno v: Inorganic Chemistry. 56:7545-7549

It has been widely believed that SrO2, a typical alkaline earth metal peroxide, should adopt the tetrahedral CaC2-type structure (space group I4/mmm) at ambient pressure. Here we report a monoclinic structure (space group C2c), as predicted from firs

Decomposition pathways of polytetrafluoroethylene by co-grinding with strontium/calcium oxides

Autor: Fumio Saito, Qiwu Zhang, Xinzhong Liu, Jun Qu, Xiaoman He

Publikováno v: Environmental Technology. 38:1421-1427

Waste polytetrafluoroethylene (PTFE) could be easily decomposed by co-grinding with inorganic additive such as strontium oxide (SrO), strontium peroxide (SrO2) and calcium oxide (CaO) by using a planetary ball mill, in which the fluorine was transfor

Thermodynamic restrictions on mechanosynthesis of strontium titanate

Autor: António Ferreira, Duncan P. Fagg, I. Antunes, Jorge R. Frade, J.F. Monteiro

Publikováno v: Journal of Solid State Chemistry. 185:143-149

Chemical potential phase stability diagrams were calculated from relevant thermodynamic properties and used to predict the thermodynamic driving force under prospective conditions of room temperature mechanosynthesis. One analysed the dependence of c

Structural Properties of Nonstoichiometric Barium and Strontium Peroxides: BaO2−x (1.97≥2−x≥1.72) and SrO2−x (1.98≥2−x≥1.90)

Autor: Markus Königstein

Publikováno v: Journal of Solid State Chemistry. 147:478-484

The crystal structures of eight single crystals of barium and strontium peroxide, prepared by high pressure–high temperature synthesis, were determined by X-ray diffraction. The crystallographic data were successfully refined in the calcium carbide

Thermal decomposition of barium and strontium peroxides

Autor: Michael J. Tribelhorn, Michael E. Brown

Publikováno v: Thermochimica Acta. 255:143-154

Isothermal TG studies of the thermal decompositions in nitrogen of barium (490–610°C) and strontium (380–530°C) peroxides to the corresponding oxides with the evolution of gaseous oxygen showed that reactions were deceleratory overall with an i

Use of thermomagnetometry in the study of iron-containing pyrotechnic systems

Autor: M. J. Tribelhorn, Michael E. Brown, M. G. Blenkinsop

Publikováno v: Journal of Thermal Analysis. 40:1123-1130

Thermal analysis is routinely used to characterize pyrotechnic fuels, oxidants and fuel/oxidant mixtures [1]. Thermomagnetometry (TM) can provide additional information if the magnetic properties of the materials change during reaction. TG, TM and DT
