Abstract

In the dielectric composition of the parent Specification either up to two thirds of the strontia is replaced by lead oxide, or up to 100% of the strontia is replaced by either calcia or baria or a mixture of calcia and lead oxide, or by a mixture of calcia, baria and lead oxide. The products are obtained by a method substantially identical with that described in the parent Specification.
