Study on Hydrolysis of Ti(SO_4)_2 during the Preparation of Titania Coated Mica Pigments
Source abstract
Abstract
The influence of the initial concentration of titanium sulfate and reaction temperature onthe preparation of mica pearl pigments was studied by chedrical analysis method. The resultsindicated that both the initial concentration and the reaction temperature are sensitive faCtors inhydrolysis. The hydrolysis product self catalyzes the hydrolysis process. Also the action energyobtAlNed from the relation of temperature and the degree of hydrolysis of Ti4+ in the preparationof pigments(91.8kJ/mol) was lower than that in the titanium sulfate solution(140.4kJ/mol).
