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

摘要

In the present invention, there is disclosed a doping frit suitable for producing electrically-conducting ceramic enamels containing 45 to 65 percent by weight of SiOi2 based on the doping frit total weight, and 55 to 35 percent by weight of a mixture of oxides that comprises: at least, an oxide of a divalent element, in a proportion, by weight, lying between 3 and 35 percent by weight; at least, an oxide of a trivalent element in a proportion, by weight, lying between 3 and 25 percent by weight; and an oxide of a doping element being selected from the group consisting of Lii2O, CuO, Sbi2Oi3, Sbi2Oi5, Bii2Oi3, Vi2Oi3, Vi2Oi5, and mixtures thereof, in a proportion, by weight, lying between 0.1 and 5 percent by weight. There is also disclosed a process for preparing the above-described doping frit, further a method of obtaining vitrifiable anti-electrostatic enamel and a corresponding ceramic product.
