  • Glazing Material
    Publication number: 20220127201
    Abstract: A glazing material for producing a glazed ceramic body, in which at a first temperature T1, the glazing material has a viscosity of more than 102.5 Pa·s, in particular more than 104.0 Pa·s, preferably more than 105.6 Pa·s and particularly preferably more than 107.0 Pa·s, and, which at a second temperature T2, which is higher than the first temperature, a viscosity of less than 109 Pa·s, in particular less than 107 Pa·s and preferably less than 105.6 Pa·s. The glazing material can be used for glazing a non-densely sintered substrate material.
