Nano Tio2

The Construction business is the major consumer of energy sources of India. Among all the materials utilized in construction, concrete is the most generally used with the ingredients extracted from the nature, except cement, and have a major impact. The basic characteristics of concrete structures and materials can be altered by adding nano materials to increase mechanical properties and other parameters. A reduction in size of particles provides an exceptional surface area-to-volume ratio and changes within the surface chemistry, surface morphology, and surface energy of the particle. If cement with nano-size particles are manufactured and processed, there will be a variety of opportunities within the fields of ceramics of high strength composites and electronic applications. Furthermore, for the fine finishing and glazing purpose where strength is not a major criteria, nano materials in blend with cement is being used widely.

In this paper, we report the comparison between nanosized TiO2 powders prepared via two different acidic conditions (i) pH2 (ii) pH4. The study presents the synthesis of nanosized TiO2 powder with anatase structure was derived from sol-gel process. Data concerning the effect of pH towards the development of TiO2 nanoparticles is reported. The samples were examined by SEM- EDAX, XRD, and FT-IR analysis. Surface morphological studies obtained from SEM micrograph. The Crystalline size of TiO2 powder has obtained for (i) pH 2 is ~3nm (ii) pH 4 is ~ 6nm at 400 ºC by controlling the acidity. In FT-IR, all the peaks observed were around 460-560 cm-1 due to stretching and bending vibrations of -OH groups. It was also found the pH of the solution affect the agglomeration of the particles
