摘要： The invention relates to a process for producing a glazed ceramic body, in which (a) a glazing material is applied to a non-densely sintered substrate material and (b) the substrate material and the glazing material are subjected to a heat treatment in a temperature range which extends from a first temperature T1 to a second temperature T2, which is higher than the first temperature, in order to obtain the glazed body. The invention also relates to the use of a glazing material for glazing a non-densely sintered substrate material.

摘要： 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.
