Abstract:
A method of coating a conductor with an insulating composition, comprising:preparing a sol-gel coating solution from 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; dipping a conductor in the sol-gel coating solution; 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 a ceramic electrically insulative coating which is one of: (1) ZrO2; (2) MgOâ€”ZrO2; (3) Y2O3â€”ZrO2; (4) CeO2â€”ZrO2; (5) In2O3â€”ZrO2; (6) SnO2â€”ZrO2, and with the ceramic coating being chemically bonded to the conductor.
