ABSTRACT:
There is a method for making a strontium titanate based Grain-Boundary Barrier Layer Capacitors (GBBLC) with improved dielectric properties by introducing an intermediate step of heat-treatment in an oxidizing atmosphere between sintering of a strontium titanate based powder in a reducing atmosphere and an infiltration of the obtained sintered body with a metal oxide.
