A process for the preparation of a niobium compound of formula (I):DNbEO&#x2003;&#x2003;(I)

Process for the manufacture of ferroelectric materials

Proton conductivity has been shown in acceptor-doped rare earth orthoniobates and tantalates (LnNbOand LnTaO) at high temperatures and in a humid atmosphere. The use of the materials as an electrolyte in a laboratory-scale fuel cell and water vapor sensor has been demonstrated. Results for Ca-doped LaNbOare given as examples.

Proton conductors

The present invention relates generally to a novel and unique class of gly materials and methods of making such materials in which substantially all of the anions are nitride ions, in contrast to the oxide ions of conventional optical glasses, or the fluoride ions of the more recently discovered fluoride optical glasses. The chemical nature of these new glasses dispose the glassy materials to a remarkable combination of desirable properties, including, but not limited to, high hardness, high refractive index and high softening temperature.
