  • 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.
    Type: Grant
    Filed: March 4, 2010
    Date of Patent: December 1, 2015

  • Patent number: 4918876
    Abstract: Molded parts are deburred by being cooled down and treated with an abrasive. The parts are cooled down and circulated by a conveying gas which circulates in a circulation chamber, while the parts are treated with an abrasive introduced into the circulation chamber.
