    摘要： The present invention provides a method for making an insulated electrical heating element such as for domestic appliances to heat water, etc. wherein a resistive track is embedded in a dielectric ceramic insulating material. The method includes the steps of providing a rigid base plate; printing a resistive track on one surface of a segment of flexible tape comprising fusible ceramic particles in an organic binder; adhering the other surface of the tape segment to a surface of a base plate; and placing a second segment of flexible tape of the same type on the surface with the resistive track printed thereon. Then the resulting assembly is fired to fuse the ceramic particles of the tape segments and provide a ceramic layer on the base plate with an electrical resistive track insulated therewithin.

    摘要： A dielectric composition including a ternary system comprising non-stoichiometric lead magnesium niobate, non-stoichiometric lead zinc niobate and non-stoichiometric lead iron niobate, and a small amount of one or more oxide additives which serves to reduce the tan .delta. value in comparison with the ternary system alone. The one or more additives may be chosen from the group consisting of nickel oxide, stoichiometric lead nickel niobate, ceric oxide, lead oxide, zirconium oxide, silver oxide, manganese dioxide, lanthanum oxide and cobalt oxide. Compositions with firing temperatures in the range 950.degree. to 1100.degree. C. have dielectric constants in the range 10700 to 16600 (at 20.degree. C.) making the composition particularly useful for high silver content multilayer ceramic capacitors.

    摘要： Conductive and porous end terminations for metal-impregnated multilayer ceramic dielectric capacitors are provided by firing a silver, or silver alloy, and glass frit onto respective end regions of a sintered capacitor stack. The exposed silver of the fired terminations is provided with a silver sulphide layer, the latter being a good electrical conductor and acting as a barrier between the silver and the impregnation metal, for example lead, during a subsequent impregnation step, whereby to prevent leaching of the silver. The termination is readily solderable by virtue of the silver sulphide layer being wetted by the lead during the impregnation step and resulting in a lead coating in the termination.
