Nanopowder Characterization Structural and morphological properties Dielectric properties Link to publisher's homepage at http://ijneam.unimap.edu.my/ Titania (TiO₂) has been widely studied because of its unique optical and chemical properties in catalysis, photocatalysis and nonlinear optics. This material crystallizes mainly in anatase or rutile phase and exhibits different physical and chemical properties. It is well-known that the anantase phase is suitable for catalyst and supports, while the rutile phase is used for optical and electronic purposes due to its high dielectric constant and high refractive index. Several methods of chemical synthesis have been developed and used to prepare thin films. Amongst the alternative methods, the Pechini method has been used successfully for the preparation of several types of materials. In this work, nanopowders of titanium oxide were prepared through the heat-treatment of metallic polymeric resin prepared by the polymeric precursor method (Pechini method). The resin was characterized by differential scanning calometry (DSC) and the powders by, X-ray diffraction (DRX) and scanning electron microscopy (SEM). Dielectric measurements were performed in function of the frequency at room temperature. 2016-03-31T04:38:42Z 2016-03-31T04:38:42Z 2010 Article International Journal of Nanoelectronics and Materials, vol.3, 2010, pages 99-111 1985-5761 (Printed) 1997-4434 (Online) http://ijneam.unimap.edu.my/ http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41230 en Universiti Malaysia Perlis |
