A hazardous waste from secondary aluminium metallurgy as a new raw material for calcium aluminate glasses.
A solid waste coming from the secondary aluminium industry was successfully vitrified in the ternary CaO-Al(2)O(3)-SiO(2) system at 1500 degrees C. This waste is a complex material which is considered hazardous because of its behaviour in the presence of water or moisture. In these conditions, the dust can generate gases such as H(2), NH(3), CH(4), H(2)S, along with heat and potential aluminoth...
متن کاملCHROMATE ALUMINATE SODALITE, Ca8[Al12O24](CrO4)2: PHASE TRANSITIONS AND HIGH-TEMPERATURE STRUCTURAL EVOLUTION OF THE CUBIC PHASE
The structural behavior of a chromate aluminate sodalite, Ca8[Al12O24](CrO4)2, at room pressure and on heating from 463 to 982°C was determined by using in situ synchrotron X-ray powder-diffraction data [ = 0.91997(4) Å] and Rietveld refinements. The sample was heated at a rate of about 9.5°C/min., and X-ray traces were collected at intervals of about 17°C. The structure at 463°C is a modulated...
متن کاملEvaluation of cytotoxicity, antimicrobial activity and physicochemical properties of a calcium aluminate-based endodontic material
UNLABELLED A calcium aluminate-based endodontic material, EndoBinder, has been developed in order to reduce MTA negative characteristics, preserving its biological properties and clinical applications. OBJECTIVES The aim of this study was to evaluate the cytotoxicity, antimicrobial activity, pH, solubility and water sorption of EndoBinder and to compare them with those of white MTA (WMTA). ...
متن کاملMaterial Study of High Performance Single Crystal Ferroelectric Nanowires
Ferroelectric materials, which exhibit switchable polarization and are piezoelectric, have been extensively studied because of their applications in nonvolatile memory and energy harvesting devices.[1,2] Recently, ferroelectric nanostructures have attracted great interest as they provide a platform to investigate the size effect of ferroelectricity and enable integration with prevailing miniatu...
متن کاملA new thermoelectric material: CsBi4Te6.
The highly anisotropic material CsBi(4)Te(6) was prepared by the reaction of Cs/Bi(2)Te(3) around 600 degrees C. The compound crystallizes in the monoclinic space group C2/m with a = 51.9205(8) A, b = 4.4025(1) A, c = 14.5118(3) A, beta = 101.480(1) degrees, V = 3250.75(11) A(3), and Z = 8. The final R values are R(1) = 0.0585 and wR(2) = 0.1127 for all data. The compound has a 2-D structure co...
