A new cleaner process to prepare pressing-powder
Sociedad Española de Cerámica y Vidrio (2011)An alternative cleaner process of pressing-powder preparation, based on filter-pressing and a novel granulation method, is presented to substitute the existing spray-drying process. In the new process, about two-thirds of ... -
Effect of particle size distribution of suspension feedstock on the microstructure and mechanical properties of suspension plasma spraying YSZ coatings
Elsevier (2015-04)In this work, aqueous suspension feedstocks with different particle size distribution from submicron- and nano-sized YSZ powders were prepared. A previous colloidal characterisation allowed concentrated suspensions (~ 40 ... -
Effect of the initial particle size distribution on the properties of suspension plasma sprayed Al2O3-TiO2 coatings
Elsevier (2015-04)Al2O3–TiO2 coatings have been deposited by atmospheric plasma spraying from agglomerated, nanostructured powders showing better properties than those of their conventional (microstructured) counterparts. These nanostructured ... -
Influence of calcium aluminate cement (CAC) on alkaline activation of red clay brick waste (RCBW)
Elsevier (2016-01)In this paper, the effect of calcium aluminate cement (CAC) additions on the alkali activation of red clay brick waste (RCBW) was studied at room temperature and at 65 °C. RCBW was partially replaced with CAC (0–50 wt.%) ... -
Influence of microstructure and magnetizing mechanisms on magnetic complex permeability (imaginary part) of a Cu-doped Ni-Zn polycrystalline ferrite
Elsevier (2021)The complex permeability of the Cu-doped Ni–Zn polycrystalline ferrites is strongly dependent on microstructure, particularly on relative density (ϕ) and average grain size (G), as it has been shown in a previous ... -
Influence of the particle size on the microstructure and mechanical properties of grains containing mixtures of nanoparticles and microparticles: Levitator tests and pilot-scaled validation
Elsevier (2013)The spray drying process is used in many industrial applications. However, different grain properties can be desirable depending on the later use of the powders produced. In this work the influence of the particle size on ... -
Microstructure and mechanical properties of grains of silica nanofluids dried in an acoustic levitator
Elsevier (2012)The microstructure and mechanical properties of spray-dried grains are key factors in many applications. In this work single droplets of silica nanofluids were dried in an acoustic levitator under different experimental ... -
Microstructure and photocatalytic activity of suspension plasma sprayed TiO2 coatings on steel and glass substrates
Elsevier (2011-10-25)In this study, TiO2 coatings were deposited by suspension plasma spraying (SPS) from a commercial TiO2 nanoparticle suspension on two different substrates: a standard stainless steel and a Pyrex glass. Coatings were sprayed ... -
El proceso de secado por atomización: formación de gránulos y cinética de secado de gotas
Sociedad Española de Cerámica y Vídrio (2013-07)Spray drying is a unit operation very common in many industrial processes. For each particular application, the resulting granulated material must possess determined properties that depend on the conditions in which the ... -
Solution precursor plasma spraying (SPPS): a novel and simple process to obtain bioactive glass coatings
Elsevier (2018)This research addresses the use of an emerging plasma spray technique known as SPPS (Solution Precursor Plasma Spraying) to obtain bioactive glass coatings. In SPPS, the feedstock is a sol precursor of the bioactive glass ...
