Abstract

We have investigated the electric properties of ceramic coating film consisting mainly of SiO₂, Al₂O₃, and TiO₂. The ceramic film on a steel plate was found to exhibit excellent adhesive stability upon heating at approximately 1000°C. In particular, film calcined in N₂ showed the higher electric resistance and lower dielectric loss factor. These results suggest that the ceramic coating material can give the best coating performance with high insulating properties by calcination in N₂.
