Concentration of TiOSO4 on Rutile White via Short Sulfate Process

Article Preview

Abstract:

Short sulfate process was developed to produce rutile TiO2 white pigment by using low concentration industrial TiOSO4 solution as raw material via self-generated seeded thermal hydrolysis route. The concentration of TiOSO4 solution had significantly influenced the structure and pigment properties of rutile TiO2 white pigment. The samples were characterized by XRD, particle size distribution and pigment properties test. Appropriate concentration of TiOSO4 was beneficial to promoting hydrolysis process in a proper way and obtaining favorable structure and high quality white pigment. The optimized concentration of TiOSO4 solution was of 191.20 g/L.
