Report

Electrophoretic mobilities of dissolved polyelectrolyte charging agent and suspended non-colloidal titanium during electrophoretic deposition

Autor: Lau, Kok-Tee, Sorrell, C. C.

Coarse (<=20 micron) titanium particles were deposited on low-carbon steel substrates by cathodic electrophoretic deposition (EPD) with ethanol as suspension medium and poly(diallyldimethylammonium chloride) (PDADMAC) as polymeric charging agent. The

Report

Morphology and photocatalytic activity of highly oriented mixed phase titanium dioxide thin films

Autor: Hanaor, D. A. H., Triani, G., Sorrell, C. C.

Publikováno v: Surface and Coatings Technology 205(12), 2011, 3658 - 3664

Thin TiO2 films on quartz substrates were prepared by spin coating of undoped and metal-ion-doped Sol Gel precursors. These films were characterised by Scanning Electron Microscopy, Laser Raman Microspectroscopy, Xray Diffraction and UV Vis Transmiss

Report

Abnormal grain growth of rutile TiO2 induced by ZrSiO4

Autor: Hanaor, D. A. H., Xu, W., Ferry, M., Sorrell, C. C.

Publikováno v: Journal of Crystal Growth; Volume 359, 15 November 2012, Pages 83-91

Abnormal grain growth (AGG) was observed in rutile TiO2 formed by the thermal treatment of anatase TiO2 in the presence of zirconium silicate. This morphological behaviour was seen to occur in sintered powder compacts and thin films with solid state

Report

The effects of firing conditions on the properties of electrophoretically deposited titanium dioxide films on graphite substrates

Autor: Hanaor, D. A. H., Michelazzi, M., Chenu, J., Leonelli, C., Sorrell, C. C.

Publikováno v: Journal of the European Ceramic Society; Volume 31, Issue 15, 2011, Pages 2877-2885

Thick anatase films were fabricated on graphite substrates using a method of anodic aqueous electrophoretic-deposition using oxalic acid as a dispersant. Thick films were subsequently fired in air and in nitrogen at a range of temperatures. The morph

Report

Anodic aqueous electrophoretic deposition of titanium dioxide using carboxylic acids as dispersing agents

Autor: Hanaor, D. A. H., Michelazzi, M., Veronesi, P., Leonelli, C., Romagnoli, M., Sorrell, C. C.

Publikováno v: Journal of the European Ceramic Society, Volume 31, Issue 6, 2011, 1041-1047

The dispersion of anatase phase TiO2 powder in aqueous suspensions was investigated by zeta-potential and agglomerate size analysis. The iso-electric point (IEP) of anatase was determined to be at pH 2.8 using monoprotic acids for pH adjustment. In c

Report

The effects of carboxylic acids on the aqueous dispersion and electrophoretic deposition of ZrO2

Autor: Hanaor, D. A. H., Michelazzi, M., Leonelli, C., Sorrell, C. C.

Publikováno v: Journal of the European Ceramic Society, Volume 32, Issue 1, 2012, Pages 235-244

The agglomeration, electrokinetic properties and electrophoretic deposition behaviour of aqueous suspensions of ZrO2 with carboxylic acid additives were studied in comparison with conventional pH adjustment. It was found that citric acid imparted neg
