Process for the preparation of glasses and glass ceramics, LAS glass and LAS glass ceramics and their use |
| abstract |
Process for the production of glasses using at least one unavoidable raw material impurity with concentrations of less than 100 ppm of arsenic and antimony-free glass mixtures and as refining agent at least one sulfate compound and SnO 2 , wherein the glass mixture comprising the refining agent is melted in a melting tank (1), is melted in a first region (10) of the melting tank (1) and carried out a primary refining, wherein the first region (10) has an average melting temperature T 1 to T 1> 1560 ° C and a mean residence time of the melt t 1 to t 1 > 2 hours is set, and the proportion of SO 3 formed by decomposition of the sulfate compound is lowered to less than 0.002 wt .-% during the execution of the primary refining, and wherein in a second region (20) of the melting furnace (1) a secondary refining is carried out at temperatures which are 50 ° C and more above the temperature of the primary refining, wherein in the second region (20) an average melting temperature T 2 to T 2 > 1640 ° C and an average residence time of the melt t 2 is set to t 2 > 1 hour. |
