  • Method of environmentally friendly melting and refining of a glass melt for a crystallizable glass of a lithium aluminium silicate (LAS) glass ceramic
    Patent number: 9199872
    Abstract: The method of environmentally friendly melting and refining a glass melt of a crystallizable glass, which is used for making a lithium aluminum silicate (LAS) glass ceramic, includes the steps of providing a glass batch with a main batch composition within a lithium aluminum silicate (LAS) glass system, in which 0.1-<0.6% by weight of tin oxide has been added as main refining agent, but which does not contain arsenic oxide and/or antimony oxide as refining agent, formulating a raw material mixture for the glass batch, so that less than 40% by weight of the raw material mixture is quartz sand and then refining a glass melt formed from the glass batch at temperatures of at least 1600° C.
