GENERATION OF AMORPHOUS CERAMIC CAPACITOR COATINGS ON TITANIUM USING A CONTINUOUS SOL-GEL PROCESS

Thin amorphous films of ceramic capacitor materials were successfully deposited using sol-gel chemistry onto titanium wire using a continuou s, computer-controlled process. By repeatedly depositing and calcining very thin layers of material, smooth and even coats can be produced. Surface analyses revealed the layered nature of these thin coats, as w ell as the amorphous nature of the ceramic. The electrical properties of the better coatings, all composed of niobrium, bismuth, and zinc ox ides, were then evaluated.
