The optimal value of the F value for titanium dioxide
Thread Content
What is the optimal control range for the F value in the hydrolysis process during titanium dioxide production? What is the difference in particle size of the material after hydrolysis between F values of 2.0–2.05 and 1.85–2.0?
A question like yours is probably impossible to answer, as it’s too vague. The effect of particle size begins with acid hydrolysis; it affects not only the F value but also stability. Simply discussing at what F value hydrolysis is optimal is meaningless
