Role of starch characteristics in the properties of low-cost ceramic membranes
Elsevier (2015)Starch is used as porosity generator in membranes and other porous ceramics. A study was conducted to evaluate the effects of the characteristics of starches (impurities, particle size), obtained from potato, pea, maize ... -
Role of suspension preparation in the spray drying process to obtain nano/submicrostructured YSZ powders for atmospheric plasma spraying
Elsevier (2015)Thermal barrier coatings were manufactured by atmospheric plasma spray process from YSZ powders. These powders were made by a reconstitution process which consists in a spray-drying of suspensions followed by thermal ... -
Shear-thinning behaviour of dense, stabilised suspensions of plate-like particles. Proposed structural model.
Elsevier (2015-09)A structural model was developed to describe the shear-thinning behaviour of dense, stabilised suspensions of plate-like particles. The model is based on the following main assumptions: the particles are distributed in ... -
Simple estimates of vehicle-induced resuspension rates
Elsevier (2011-10)Road dust emissions are considered to be a major source of airborne particulate matter (PM). This is particularly true for industrial environments, where there are high resuspensionrates of deposited dust. The calculation ... -
Sinter-crystallisation kinetics of a SiO2–Al2O3–CaO–MgO–SrO glass-ceramic glaze
Elsevier (2020-03-15)This paper examines the microstructural development and kinetics of the sintering and crystallisation processes of a SiO2–Al2O3–RO (R = Ca, Mg, Sr) glass-ceramic glaze. Crystallisation and sintering kinetics were studied ... -
Sintered microstructure effect on RF-wave shielding properties of a Cu-doped Ni–Zn-polycrystalline ferrite
Elsevier (2021)The shielding properties of a Cu-doped Ni–Zn polycrystalline ferrite in the frequency range 1 MHz to 1 GHz were explored. Samples of composition (Cu0.12Ni0.23Zn0.65)Fe2O4 were prepared by the traditional ceramic route. The ... -
Sintering of raw glazes for floor and porcelain tiles: A non-isothermal kinetic model
Elsevier (2016-11)New fritless glaze compositions have been developed for floor and porcelain tiles from a new boron raw material obtained by calcination. The complexity of this type of composition also translates into complex behaviour ... -
