Microstructure and photocatalytic activity of APS coatings obtained from different TIO2 nanopowders
(Elsevier, 2013-04)
In recent years, intense research has shown that thermal spray techniques, especially atmospheric plasma spraying (APS), can be used to obtain nanostructured TiO2 coatings with effective photocatalytic activity.

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 ...
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 ...
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 ...
Relationship between certain ceramic roofing tile characteristics and biodeterioration
(Elsevier, 2011)
This paper examines the relationship of certain red ceramic roofing tile properties to roofing tile biodeterioration. The following properties were studied: apparent porosity, roughness, and the presence or absence of two ...
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 ...
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 ...
Revestimentos cerâmicos: acima e além das aplicações tradicionais
(Associação Brasileira de Cerâmica, 2008)
Nos últimos anos os revestimentos cerâmicos têm seguido a mesma tendência de inúmeros outros produtos dos chamados setores industriais tradicionais: a busca de novos usos e aplicações, que permitam ampliar seus mercados ...
Nanoindentation study of the mechanical and damage behaviour of suspension plasmasprayed TiO2 coatings
(Elsevier, 2012-01)
TiO2 coatings can be used as self-cleaning surfaces owing to their photocatalytic and hydrophilic properties. Suspension plasma spray (SPS) has proven to be a feasible and cheap technique for producing self-cleaning surfaces ...
