Doping frit suitable for producing electrically-conduction ceramic enamels and process for producing thereof

The frit contains a doping substance, preferably antinomy oxide, at a quantity lying between 0.1 and 5 % by weight, that, mixed with a semiconducting oxide, such as tin oxide, allows, on a ceramic product, a vitrifiable anti-electrostatic enamel to be obtained. The semiconducting oxide, on being inc...

Zusammenfassung:The frit contains a doping substance, preferably antinomy oxide, at a quantity lying between 0.1 and 5 % by weight, that, mixed with a semiconducting oxide, such as tin oxide, allows, on a ceramic product, a vitrifiable anti-electrostatic enamel to be obtained. The semiconducting oxide, on being included in the vitreous phase component of the ceramic matrix gives this a resistance less than 10 OMEGA .cm. These frits are especially applicable to the production of enamelled or sinterised ceramic pieces, for example, floor tiles.
