Abstract
An electric device, apparatus, circuit, or the like incorporates as a conducting member a titanium refractory having such conductivity by virtue of its preparation from a material consisting of or containing titanium dioxide that the specific resistance of the member decreases as the applied potential difference increases. The non - linear current voltage characteristics depend on the terminal contacts, which may be of silver, copper, mercury, lead, platinum or gold, and are preferably formed in coherent contact, e.g. by spraying, "firing-on" or cathodic dispersion. The specific resistance with alternating current is lower the higher the frequency. Specification 467,113 is referred to.
