The effect of aluminum sulfate as salt treatment agent on the properties of titanium dioxide initial products,mainly including the rutile conversion rate,achromatic energy,whiteness and particle morphology,was studied. The results show that aluminum sulfate is inhibitor of rutile transformation and has almost no effect on achromatic energy of titanium dioxide initial products with content of 0.08%~0.28%. The whiteness value of titanium dioxide initial products increases with increasing aluminum salt content in the range of 0.05%~0.10%,while it continuously decreases with increasing aluminum salt content in the range of 0.10%~0.50%. It is also found that addition of aluminum sulfate favors the growth of tetragonal system particles for titanium dioxide.
