Preparation of Monosized Titanium Dioxide Powder from TEOT
The controlled Ti(CO2H5)4 hydrolysis reactions for the synthesis of Spherical Monodispersed Titania powders are described. Increasing the concentration of TEOT and the molar ratio of water to TEOT in alcohol solution decrease the reaction time and the particle size. The reaction time is delalyed by increasing the chain length and the number of carbon branches of alcohol as a solvent. The prepared powders with an average diameter of 0.8$mu$ and the spherical monodispersed transfer to Rutile phase at 55$0^{circ}C$.
