  • Patent number: 8783065
    Abstract: A method for bending radiation shielding glass which has a heavy metal oxide content of at least 50% by weight is provided, wherein first a mold is provided, a glass plate comprising a radiation shielding glass is then provided, the mold is preheated to a temperature of 300 to 400° C., the glass plate is placed on the mold, the glass plate and the mold are heated in a furnace to a temperature of 370 to 430° C., then heated together to a temperature of 400° C. to 500° C., preferably to 440 to 500° C., the total heating time being at least 30 minutes, preferably at least 60 minutes, the glass plate is then molded and finally the molded glass is cooled by means of a cooling program over a period of at least 60 minutes. For thermal prestressing, the glass body is supported at least at its outer periphery at a number of support points, introduced into a preheated furnace, heated to 400 to 500° C.

  • Publication number: 20050095404
    Abstract: The method of making a knobbed glass or glass ceramic plate includes placing a glass or glass ceramic plate on a support having knob-shaped elevations and/or depressions; jointly heating the plate and the support over a transformation temperature of the glass or glass ceramic plate and, advantageously after a certain time interval, subsequently cooling the plate to room temperature. The glass or glass ceramic plate with knobs made by the method is also part of the invention. The glass or glass ceramic plate with the knobs can be used in heating units, such as baking ovens, for thermal isolation or decoupling of differently heater spatial regions. Also it can be provided with a germ killing coating for use in an air conditioning unit to clean air.
