Anti-reducing semiconducting porcelain having a positive temperature coefficient of resistance |
| abstract |
ABSTRACT OF THE DISCLOSURE Anti-reducing semiconducting porcelain having a positive temperature coefficient of resistance comprises a barium titanate composition, and a flux containing 0.14 to 2.88 parts by weight of TiO2, 0.1 to 1.6 parts by weight of Al2O3 and 0.1 to 1.6 parts by weight of SiO2 per 100 parts by weight of the barium titanate composition. It has a high positive temperature coefficient of resistance which does not show any appreciable change in the presence of a reducing atmosphere, such as hydrogen gas or gasified gasoline. It need not be isolated from a reducing atmos-phere by a plastic or metallic enclosure, but can be exposed thereto. The flux may further contain a zinc, potassium or lithium compound. |
