Abstract:
A conductor having a ceramic electrically insulative coating, comprising:said insulative coating having been applied by dipping the conductor in a sol gel coating solution made up of one of; 1) Zirconium tetrabutoxide; 2) Zirconium tetrabutoxide and Magnesium 2,4-pentadionate; 3) Zirconium tetrabutoxide and Yttrium nitrate; 4) Zirconium tetrabutoxide and Yttrium isoproxide; 5) Zirconium tetrabutoxide and Cerium (III) 2,4 pentadionate; 6) Zirconium tetrabutoxide and Indium oxide; 7) Zirconium tetrabutoxide and Indium isoproxide; and 8) Zirconium tetrabutoxide and Tin oxide; a solvent; and a catalyst; drying the dip coated conductor at a temperature and for a time sufficient to evaporate the solvent and catalyst; and heating the conductor in an oxygen containing atmosphere at a temperature and for a time sufficient to result in the ceramic electrically insulative coating which is one of 1) ZrO2, 2) MgOâ€”ZrO2, 3) Y2O3â€”ZrO2, 4) CeO2â€”ZrO2, 5) In2O3â€”ZrO2, and 6) SnO2â€”ZrO2, and the ceramic coating being chemically bonded to the conductor.
