Structure and catalytic properties of sulfated zirconia foams
(Springer, 2014-11-01)
Porous sulfated zirconia foams were manufactured by a simple methodology based on the sol-gel process combined with a liquid foam template that used a surfactant mixture. A block copolymer (Pluronic F-127) and an anionic ...
Aproveitamento de resíduos sólidos de alumina na produção de espumas cerâmicas
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2019-11-29)
Alumina has been used as raw material for ceramics agricultural pieces field material due its excellent properties. However, these pieces production results in waste generation, fact that motivated this study to search an ...
Efectos de la temperatura de calcinación y la carga de carboximetilcelulosa de sodio en la síntesis de nuevas espumas de cerámica de bentonitaEffects of the calcination temperature and the load of sodium carboxymethyl cellulose in the synthesis of novel bentonite ceramic foams
(Asociación Argentina de Energía Solar, 2017-12)
Novel ceramic foams were obtained by the replica method, using bentonite as alternative rawmaterial and polyurethane sponge as template, where the latter also controls the distribution ofthe pore size of these ceramics. ...
NiO-based ceramic structured catalysts for ethylene production: Substrates and active sites
(Elsevier Science, 2020-09)
Structured catalysts have important advantages compared to powder formulations and they are required for processes intensification. In this work, three different ceramic structures: a cordierite monolith, an alumina foam ...
Eggshells as agro‐industrial waste substitute for CaCO3 in glass foams: A study on obtaining lower thermal conductivity

Formation of zirconia foams using the thermostimulated sol-gel transition
(Elsevier B.V., 2002-06-01)
In this paper we describe the production of zirconia-based foams by a novel thermostimulated sol-gel route, that employs the foaming of colloidal suspensions prior to the sol-gel transition promoted by small increase of ...

EFFECT of DIFFERENT SOLID AMOUNTS IN THE PHYSICAL and MICROSCOPICAL PROPERTIES of SiC POROUS CERAMICS
(Trans Tech Publications Ltd, 2008-01-01)
The presence of pores in ceramics is directly related to the chosen forming process. So, in the starch consolidation method, the ceramics show, after burning, pores with morphology similar to that presented by this organic ...
