Comparison of freeze drying and spray drying to obtain porous nanostructured granules from nanosized suspensions
Elsevier (2012)This work studies the spray drying and freeze drying of different nanosized ceramic materials and the physicochemical characteristics of the obtained granules. Colloidal suspensions of alumina, titania, and a 87/13 mixture ... -
Dispersion of TiO2nanopowders to obtain homogeneous nanostructured granules by spray-drying
Elsevier (2011)This work deals with the dispersion and stabilisation of nanosized TiO2 particles in an aqueous medium as a first step in the preparation of spray-dried nanostructured powders. A colloidal route leading to the production ... -
Effect of slurry properties and operational conditions on the structure and properties of porcelain tile granules dried in an acoustic levitator
Elsevier (2012)Spray-drying is a unit operation highly important in many industrial applications. In this work, the influence of the drying conditions on the final grain properties has been investigated in single droplet experiments.Porcelain ... -
Influence of Particle Size on the Drying Kinetics of Single Droplets Containing Mixtures of Nanoparticles and Microparticles: Modeling and Pilot-Scale Validation
Taylor & Francis (2013-05-03)The particle size of the primary particles is an important parameter influencing the drying behavior of droplets. In this work, the influence of particle size on the drying kinetics and grain properties was analyzed for ... -
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 ... -
Modeling of Drying Curves of Silica Nanofluid Droplets Dried in an Acoustic Levitator Using the Reaction Engineering Approach (REA) Model
Taylor & Francis (2013)The use of nanoparticles has become of great interest in different industrial applications. The spray drying of nanofluids forms nanostructured grains, preserving the nanoparticle properties. In this work, individual ... -
Preparation of high solids content nano-titania suspensions to obtain spray-dried nanostructured powders for atmospheric plasma spraying
Elsevier (2012)Nanosized TiO2powder with an average primary size of ∼20 nm and surface area of ∼50 m2/g (Aeroxide®P25, Degussa-Evonik, Germany) was used as starting material. A colloidal titania suspension from the same supplier was also ... -
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 ...
