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 ...
Dispersion of mixtures of submicrometer and nanometre sized titanias to obtain porous bodies
(Elsevier, 2013-12)
The stability and rheological behaviour of bimodal titania suspensions was studied. Bimodal mixtures were prepared by mixing nanosized TiO2 powders with an average primary size of ∼20–40 nm and surface area of ∼50 m2 g−1 ...
Study of colloidal behaviour and rheology of Al2O3-TiO2 nanosuspensions to obtain free-flowing spray-dried granules for atmospheric plasma spraying
(Elsevier, 2013-09)
This work deals with the dispersion and stabilisation of nanosized Al2O3 and TiO2 particles in aqueous medium. The dispersing conditions were studied as a function of pH, dispersant content, solid loading and ageing.

Atmospheric plasma spraying coatings from alumina–titania feedstock comprising bimodal particle size distributions
(Copyright © Elsevier, 2013)
In this work, Al2O3–13 wt% TiO2 submicron-nanostructured powders were deposited using atmospheric plasma spraying. The feedstocks were obtained by spray drying two starting suspensions of different solids content, prepared ...
Alumina-zirconia coatings obtained by suspension plasma spraying from highly concentrated aqueous suspensions
(Elsevier, 2016)
Suspension plasma spraying (SPS) deposition represents an innovative technique to produce coatings that exhibit improved properties. However, the key to obtain coatings with superior functional properties relies on the ...
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 ...
Characterization of silica–water nanofluids dispersed with an ultrasound probe: A study of their physical properties and stability
(Elsevier, 2012)
The stability and agglomeration state of nanofluids are key parameters for their use in different applications. Silica nanofluids were prepared by dispersing the nanoparticles in distilled water using an ultrasonic probe, ...
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 ...
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 ...
ZrSiO4/ZrO2 thermal barrier coatings produced by suspension plasma spraying
(Elsevier, 2024-01-01)
Zircon has excellent thermal properties that make it a good candidate for thermal barrier coatings. Although it suffers decomposition at high temperature, significant amounts of zircon phase can be retained in the coatings ...
