Abstract
Electrodes particularly for igniters use for igniting combustible mixtures in I.C. engines, gas turbines and jet engines, wherein the erosion resistance is improved and the risk of failure reduced by virtue of at least a part of the working surface of each electrode comprising one or more intermetallic compound of the general formula AxBy where A is Be, Al, Sc, Y, one of the lanthanides, Si, Ti, Zr, Hf, Th, V, Nb, or Ta and B is Ru, Rh, Pd, Ir or Pt and where x and y are integers >/=1 and preferably </=5.
