ABSTRACT:
A ceramic electric resistor and a method for making the same. The resistor has a body which is formed of a material having a Perovskite structure with semiconducting doping and on its surface is contacted with two layers of different materials. The first layer is palladium or in association with palladium chloride and the second layer is one from a group of nickel, nickel-phosphorus or nickel-boron alloys. The process includes stoving-in the palladium or palladium chloride solution and providing a given composition of nickel bath for the second layer.
