| Abstract: | Nelles'synthesis method of Ti(OEt)_4has been improved. Preparation of high-purity,fineand monodisperse TiO_2 powders via the hydrolysis ofTi(OEt)_4 is studied by using self-derived fresh Ti(OEt )_4.The physico-chemical properties of the TiO_2micropowder and electro-characters of PTC resistorsmade from these TiO_2 powders meet with thetechnical demands of electroceramic factories.Investigations show that titanium alkoxide hydrolysis is a good method for the preparation of TiO_2 powdersand TiO_2 based ceramics. |
