摘要
rn this work the influence of the type of the titanium alkoxide and the type and concentration of the peptizing agent on the powder crystallization is pointed out. Anatase or rutile phases are directly precipitated from the sol during ageing in case of the use of hydrochloric or nitric acid as peptizing agent. If tetraethylammonium hydroxide is used the sol is very stable and an amorphous powder is only obtained after drying at 100 degrees C. The sols and obtained powders were characterized.
