Study The Molarity Influence on the structural properties of titanium oxide (TiO2) Prepared with (Sol_Gel)

Abstract

This report was conducted to study the molar effect on structural characteristics of Titanium dioxide TiO2 ,the deposition of films on glass substrates was done by using sol gel solution with Spin-Coting method (speed =3000 rpm) during 30 sec of the deposition where the solution have been prepared using Titanium hydroxyl Material Ti[O(CH2)3(CH3)]4 and C4H11NO2 as Fixative and Ethanol as a solvent. we have prepared different concentrations of solution (0.05, 0.10 , 0.15, 0.20, 0.30) M ,the films have been annealing with temperature (500 °C), we have investigated the Structural characteristics using (XRD,AFM and SEM) analyses. The (XRD) results have shown that the Anatase phase is the prevalent phase when the concentrations (0.05 and 0.10)M and after increase the concentration start changes gradually from Anatase phase to Rutile phase when the concentration (0.2)M. The SEM analyses have approved that the film has good topography. The granules had a rhombus form then its shape became cluster with the increasing of concentration . The (AFM) have shown that the membranes had nano- thickness,and they are soft with good coating
