Abstract :Characterizations of high temperature ceramic insulation coatings were investigated by surface conductivity, electric strength, dielectric constant, mass lost and corrosion techniques. MgO-ZrO 2 was coated on Stainless-Steel-304 insert ignore into journalissuearticles values(SS); tapes by reel-to-reel sol-gel process for investigation of characterizations of MgO-ZrO 2 as insulation coatings. Tapes were produced several dips for application of HTS/LTS high field insert coils and magnets. Solutions were prepared by using Mg and Zr based precursors, solvent and chelating agent, then the insulations was coated on long-length SS substrate. Characterizations of electrical strength and dielectric constant were tested by using standardization equipment. Thermogravimetric insert ignore into journalissuearticles values(TGA); analyzes in air and in nitrogen was done. The effect of corrosion test according to the standardization of ASTM B 117 was studied. Surface morphology of micrographs of corrosion test samples was examined using ESEM.
