Semiconductive ceramic composition.

摘要

A semiconductive ceramic composition capable of permitting its resistance-temperature characteristics and resistance to be controlled as desired and a firing temperature of the composition to be lowered to a degree sufficient to facilitate the mass-production at a low cost. The composition contains a main component consisting of SrO, PbO and TiO2 and is subjected to firing in an oxidizing atmosphere. The composition may contain at least one of SiO2 and M as a minor component. A variation in amount of the main and minor components permits characteristics and properties of the composition to be varied as desired.
