Fundamental Study of the Influence of Electroless Nickel Plating on PTC Effect in BaTiO3-based Ceramics

Abstract

Abstract: A fundamental study of the influence of electroless nickel plating on PTC effect in some semiconducting ceramics of (Ba_1-xPb_x)TiO₃ was made by comparison experiment. It was discovered that in some dense PTC ceramics the influence of nickel plating was not due to the permeation of plating solution into the ceramics, but was related to the reactions in the course of nickel plating. It was first proposed in this paper that nascent hydrogen generated in nickel plating could have influence on PTC effect.

Key words: electroless plating, PTC effect, ceramics
