Abstract: 946,891. Temperature dependent resistors. SIEMENS & HALSKE A.G. April 9, 1962 [Feb. 2, 1962], No. 13515/62. Addition to 911,741. Drawings to Specification. Heading H1K. In an improvement of the invention claimed in the parent Specification in which a resistor, comprising ceramic ferro-electric material to which impurity conductivity has been imparted, has a positive temperature coefficient of resistance, the said material includes an oxide of a tetravalent metal and the surface of the resistor is reduced before a metal contact is attached thereto. It is stated that by reducing the surface, e.g. by electrolytically depositing hydrogen thereon or by subjecting it to a glowdischarge, tetra-valent oxides are reduced to trivalent oxides, e.g. Ti 2 O 3 - #TiO 2 , to which the more usual contact metals, e.g. Cu or Ag, will form an ohmic rather than a rectifying connection and consequently the varistor effect normally experienced when these metals are used as contacts will be diminished or even eliminated. In the example given, titanium oxide in a barium titanate ferro-electric material is reduced as aforementioned and a copper electrode is then deposited either electrolytically or by vapour deposition.
