Definitions

  • Titanium metal was exposed to acetylene for a period of 1 half hour at a temperature of 950 degrees C, yielding a layer of a thickness of about 2 um. Resistance - 90 milliohms at 100 grams.
  • the invention does not depend upon designation of compound composition.
  • the technical literature includes reports of compoumds with measured electrical properties and Known stability in some encountered ambients so, for example, titanium nitride has been studied to result in a literature reference, 1980 Proceedings of the Electrochemical Society, 316 (1979), reporting bulk resistivity values of 50 ⁇ cm.
  • the compound is known to be stable in usual air ambient over usually prescribed temperature ranges of operation.
