Structural characterization of pure Na-nephelines synthesized by zeolite conversion route
(Journal of Physics and Chemistry of Solids, 2004)
Using the zeolite thermally induced transformation route and starting from Na-LTA, Na-FAU and Na-GIS zeolites as precursors, we synthesized pure sodium nephelines (ps-Ne) with Si/Al ratios between 1.0 and 1.5 (ps-NeLTA, ...
The influence of mechanical activation on the stoichiometry and defect structure of a sintered ZnO-Cr2O3 system / The influence of mechanical activation on the stoichiometry and defect structure of a sintered ZnO-Cr2O3 system
(Zurich : Trans Tech Publications, 2004)
Mixtures of starting ZnO and Cr2O3 powders in equimolar quantities were mechanically activated by grinding using a high energy vibro-mill for 0, 40 and 80 minutes. Qualitative X-ray diffraction analysis made after sintering ...
Spectrophotometric study of the anodic corrosion of Ti/RuO2 electrode in acid sulfate solution
(Elsevier Ltd., 2004)
Electrochemical properties of RuO2-based electrode, particularly the oxygen evolution and anodic dissolution of RuO2 have been investigated in 0.5 mol dm-3 H2SO4 solution by means of polarization measurements and product ...
Electrolytic Hydrogenation of Glucose on Amalgamated Zinc in Sulphate Solutions
(Zurich : Trans Tech Publications, 2004)
The kinetics of the hydrogen evolution reaction (HER) and electrolytic glucose reduction (EGR) to sorbitol was investigated at an amalgamated Zn electrode (AZE) in sulfate solutions. In the presence and the absence of ...
A phenomenological analysis of sintering kinetics of alumina
(Durnten-Zurich : Trans Tech Publications, 2004)
In this paper a phenomenological analysis of the sintering kinetics of alumina powder compacts with different proportions of small and large particles has been made. A phenomenological approach enables definition of ...
