Application of sol-gel technology to produce aluminium titanate. In: INTERNATIONAL CONFERENCE ADVANCED ON MATERIAL, September 20-25, 2009, Rio de Janeiro, RJ. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/13140.http://repositorio.ipen.br/handle/123456789/13140The ceramic raw materials, aluminum titanate (- AlTiO5), were prepared by the sol-gel method. To produce aluminium titanate powder, aluminum and titanium alkoxides were used as precursors with the addition of hydrochloric acid aiming to produce a translucent gel to minimize the precipitate formation. The most translucent gel obtained showed, by thermal treatment, a typical structural evolution: the direct crystallization of the aluminum titanate phase at 900o C. At this temperature the aluminum titanate phase was detected after 3 hours treatment. At 900 o C after 5 hours treatment, the phase became well crystallized without any change in its characteristics within 10 hours treatment. At 1400 o C occurred the formation of aluminium titanate in all samples.The sol-gel method minimized residual -alumina and rutile phases when compared to the conventional method of oxide admixtures.openAccessaluminiumtitanatessol-gel processpowdersheat treatmentsx-ray diffractionTexto completo de eventohttps://orcid.org/0000-0002-2147-8295https://orcid.org/0000-0001-8542-3827
