The meta-titanic acid was prepared by hydrolysis with adding crystal seeds,and the influences of curing time,curing methods and stirring time on the particle size and distribution of meta-titanic acid were studied.The variations of particle size and quantity of the product in hydrolysis process were moni-tored online by focused beam reflectance measurement (FBRM),and the particle size and distribution of the hydrolysis product were measured by laser particle size analyzer.The results show that both of the par-ticle mean diameter and the proportion of large particles increase with the increment of curing time,and the meta-titanic acid with suitable size and uniform distribution can be obtained by stirring and no-heating in the curing period.The particle size of meta-titanic acid firstly decreases and then increases with in-crease of stirring time in curing period.
