Abstract:
This Final Technical Report covering the three-year period from December 1, 1990 to November 30, 1993 presents a summary of research performed on two classes of materials obtained by the sol-gel method. Single crystal thin films were successfully prepared for the, ferroelectric materials KNbO3 and LiNbO3. A new phenomenon, Amorphous Ferroelectricity was discovered. Organically Modified Silicates Ormosils were further developed to give enhanced high temperature rubbery elasticity. A theory was developed for the calculation of the hardness of Ormosils. By modifying the Ormosils with Ti, Zr and Al to replace Si, Vickers Hardness of over 200 Kgsq mm 2 was obtained. This is about ten times that of the hardness of the hardest transparent organic plastics. Sol- Gel Science, Ferroelectrics, Organically modified ceramics.
