Description:

Single and mixed phase TiO2 powders prepared by excess hydrolysis of titanium alkoxide To investigate the excess hydrolysis of titanium alkoxides, TiO2 powders were fabricated from titanium tetraisopropoxide using 6 : 1 and 100 : 1 H2O/Ti (r) ratios. The powders were dried and fired at a range of temperatures ((800uC). Hydroxylation and organic content in powders were characterised using attenuated total reflectance. This paper presents a useful study for those wishing to fabricate titanium dioxide powders by hydrolysis of organometallic precursors.
