On hydrolysis process by optimizing the process index from controling the plus seed activity, temperature, concentration, acidity, ferrotitanium ratio and stirring velocity, have greatly improved the quality of hydrolysis. Hydrolyzed metatitanic acid particle size becomes finer, and particle size distribution is more optimized; hydrolysis rate, basically stable at around 95% ; The washing effect of hydrolyzed metatitanic acid material is superior to the former.
