Abstract
The influence of surface properties, including fineness, total pore volume, specific surface area and zeta potential on viscosity of TiO2 slurry were studied. The viscosity and these surface properties of TiO2 samples were respectively measured by viscometer, standard sieve, specific surface area analyzer, particle size analyzer. The results show that with increase of fineness and absolute value of zeta potential, the viscosity of TiO2 slurry decrease gradually, but with increase of total pore volume and specific surface area, the viscosity of TiO2 slurry also increase. The suitable conditions in low viscosity of TiO2 slurry are as follows: fineness and absolute value of zeta potential is respectively greater than 0.1%, 70mV; total pore volume and specific surface area is respectively less than 0.05cc/g, 7.5m2/g
