Thick film silver compositions for silver terminations for reduced barium titanate capacitors

摘要

Thick film silver compositions, containing silver powder, glass and certain inorganic materials, useful for silver terminations for reduced barium titanate (RBT) capacitors, are provided. The inorganic materials or their precursors contain ions capable of substituting into the BaTiO3 lattice, existing as surface layers on the RBT bodies, or grains therein, to produce (Ba1-xMx') (Ti1-yMy'')(O3-zAz) where x<1, y<1, and z<0.1. When terminated with these thick film silver compositions, RBT capacitors have excellent dielectric properties.
