Abstract

Nanosized titanium oxide (TiO2) powders have been prepared by conventional and microwave hydrothermal methods by forced hydrolysis of TiOCl2. As-prepared powders have been completely characterised by qualitative and quantitative XRD and TEM. The obtained titania powders have been redispersed (45 and 60 wt%) in an aqueous hydroxypropylcellulose (HPC) solution (0.5-1 wt%) and rheometry has been performed in order to evaluate the influence of HPC on particles agglomerations. Moreover, the effect of mixing time, HPC and TiO2 concentration and their mutual interactions on apparent viscosity have been evaluated with a Design Of Experiment (DOE) approach.
