In order to measure the particle size distribution(PSD) of metatitanic acid slurry, hydrolyzed from sulfate titanium dioxide process, the influencing factors of dispersion methods and measurement conditions on the PSD of metatitanic acid were investigated by photon correlation spectroscopy(PCS).Dispersion medium, dispersant and its dosage, metatitanic acid dosage, ultrasonic dispersion time and stabilization time were studied to determine the optimum dispersion condition.The results showed that the optimum dispersion condition for the measurement of the particle size distribution of hydrated metatitanic acid by PCS is using distilled water as dispersion medium, 50 mL sodium hexametaphosphate of 0.05% as dispersant, hydrolyzed metatitanic acid about 0.044 g, and then measuring the PSD immediately after ultrasonic dispersion time 5 min.
