Abstract:
    Material forming dielectric ceramics includes an oxide containing a component A and a component B. The component A is selected from a group of lead, calcium, strontium, and barium. The component B is selected from a group of magnesium, nickel, titanium, zinc, niobium, and tungsten. The component A includes lead and at least one of the other substances. The component B includes at least two of the substances. A ratio between values a and b is chosen so that a/b
