Anwendungen & Verwendung
Verwenden
Titanium ethoxide is used widely as a precursor for the synthesis of Ti4+ ions titania nanoparticles by various techniques such as :in the sol-gel synthesis of free-standing ferroelectric lead zirconate titanate nanoparticlesspherical titania cores, produced either by hydrolysis of Ti(IV) ethoxide droplets in contact with water vapor or by preadsorption of the titanium alkoxides into/onto the clay mineral platelets and their subsequent hydrolysis and calcination.
