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.
Claims15
A glazing material for producing a glazed ceramic body that is a glazed dental body, in which the glazing material comprises 14 to 30 wt.-% Al2O3 and up to 2.25 wt.-% Na2O and in which, at a temperature of 950° C., the glazing material has a viscosity of more than 107.0 Pa·s, at a temperature of 1300° C., a viscosity of more than 104 Pa·s and, at a temperature of 1450° C., a viscosity of less than 109 Pa·s, wherein the glazing material is in the form of a powder, a slip, a spray or a lacquer or is incorporated into a film or an adhesive strip.
A glazing material for producing a glazed ceramic body that is a glazed dental body, in which the glazing material contains 14 to 30 wt.-% Al2O3 and up to 2.25 wt.-% Na2O and in which, at a temperature of 950° C., the glazing material has a viscosity of more than 107.0 Pa·s, at a temperature of 1300° C., a viscosity of more than 104 Pa·s and, at a temperature of 1450° C., a viscosity of less than 109 Pa·s, wherein the glazing material is in the form of a powder, a slip, a spray or a lacquer or is incorporated into a film or an adhesive stripand wherein the glazing material allows direct glazing of non-densely sintered substrates without the glazing material penetrating into the substrate material.
