Influence of Tungsten Dopant on Sintering and Curie Temperatures of Ba(Zr0.10Ti0.90)O-3 Ceramics
(Taylor & Francis Ltd, 2008-01-01)
Ba(Zr0.10Ti0.90)O3 (BZT10) and W+ 6 substituted BZT ceramics (BZT10:W) were prepared by mixed oxide method. The effect of W+ 6 addition in the BZT was evaluated by X-ray diffraction (XRD), dilatometer analysis, microstructural ...
Non-isothermal kinetic of oxidation of tungsten carbide
(Springer, 2014)
On-line mass spectrometry of the electro-oxidation of methanol in acidic media on tungsten carbide
(SPRINGER, 2008)
The electro-oxidation of methanol at supported tungsten carbide (WC) nanoparticles in sulfuric acid solution was studied using cyclic voltammetry, potentiostatic measurements, and differential electrochemical mass spectroscopy ...
Structural and electrochemical behavior of tungsten oxide obtained by solid state reaction
(Elsevier Science BvAmsterdamHolanda, 2006)
Detection of H2facilitated by ionic liquid gating of tungsten oxide films
(2022-01-01)
Molecular hydrogen (H2) shows promise as a future renewable energy carrier. However, due to safety concerns, its reliable detection in different atmospheres is an important issue. Here, we propose a hydrogen sensor based ...
Nano-yttria in oxide dispersion strengthened tungsten under alpha particle irradation
(Elsevier, 2019-08)
Oxide dispersion strengthened (ODS) alloys, particularly steels and tungsten with yttria nanoparticles, have been proved to be a new class of high-strength nuclear material. We developed a simple model of an ODS tungsten ...
Preparation and characterization of Mo/W bimetallic carbides by using different synthesis methods
(SPRINGER, 2008)
Molybdenum and tungsten bimetallic oxides were synthetized according to the following methods: Pechini, coprecipitation and solid state reaction (SSR). After the characterization, those solids were carbureted at programmed ...
