摘要

Glazing is applied to a ceramic material by an electric field which applies the glazing in a dry state as a prepared powder in a size range of 80 microns and with an electric resistivity of 1010 ohm/m, pref. 1010-1013 ohm/m. The powder is prepared by enclosing the particles with methy hydrogen polysiloxane in a mass ratio of 0.1%, with an addition, to the coating material, to 5-10% of dibutyl tindilaurate or cobalt naphthenate. the powder is applied in an electric field at a voltage of 50 kV and the glazing is finally fired at 800 degrees C-1000 degrees C. This serves the two firing operations which are needed when the glazing is applied wet on a fired ceramic article. The new system thus saves up to 50% of the power consumption and over 50% of the glazing material per unit surface area.
