Tungsten carbide is a very effective insulator. It is used as an 
abbrasive and protective coating.

  I am assuming you meant elemental tungsten metal (as used in Spark 
gaps).  Tungsten is a lousey conductor of electricity, but in the short 
stub length we use in Rotary gaps, its resistance is of no concern 
whatsoever.
