The relationship between pH value and rheological properties of TiO2 suspensions was examined and its mechanism was studied by means of measuring the surface potential of TiO2. The number of acid and alkali OH groups was determined by the difference of H+ or OH- before and after TiO2 addition. The number of OH groups was also measured by other method and the results are fair.
