Publication number: 20210403365Abstract: Sheet-like glass ceramic article are provided that include surfaces with a thickness between the surfaces between 0.5 mm and 1.9 mm and a core. The articles have a first microstructure provided on each of the surfaces and have a second microstructure in the core with a second thickness (d2). The first microstructures extend inwardly from the surfaces towards the core and has a first thickness (d1). The first microstructure has a difference from the second microstructure selected from a group consisting of: a crystalline phase type, a crystalline phase amount, crystalline phase size distribution, crystalline phase orientation, crystalline phases composition, crystalline inclusion, an amorphous phase type, an amorphous phase percentage amount, an amorphous phase composition, and any combinations thereof. The difference results in a first coefficient of linear thermal expansion of the first microstructure that is smaller than a second coefficient of linear thermal expansion of the second microstructure.Type: ApplicationFiled: June 30, 2021Publication date: December 30, 2021Applicant: SCHOTT AGInventors: Falk Gabel, Roland Dudek, Evelin Weiss

Patent number: 10239779Abstract: A glass ceramic article is provided so that a reliable coloring with a defined transmittance is ensured. The reliable coloring of the glass ceramic article is based on a high content of iron oxide of more than 0.1 percent by weight which itself has a strongly coloring effect does not further reduce transmittance but rather interacts with vanadium oxide to attenuate the absorption caused by vanadium oxide.Type: GrantFiled: December 29, 2014Date of Patent: March 26, 2019Assignee: SCHOTT AGInventors: Falk Gabel, Friedrich Siebers, Evelin Weiss

Glass ceramic substrate made of a transparent, colored LAS glass ceramic and method for producing it
Patent number: 10183888Abstract: A glass ceramic substrate made of a transparent, colored LAS glass ceramic is provided. The glass ceramic has a gradient layer with keatite solid solution and an underlying core with high-quartz solid solution as predominant crystal phase. The keatite solid solution in a depth of 10 ?m or greater exceeds 50% of the sum of the high-quartz solid solution proportion and keatite solid solution proportion. The ceramization includes a crystal transformation step, in which the high-quartz solid solution is transformed at a maximum temperature in the range of 910° to 980° and a time period of between 1 and 25 minutes in part into the keatite solid solution.Type: GrantFiled: December 23, 2015Date of Patent: January 22, 2019Assignee: SCHOTT AGInventors: Falk Gabel, Oliver Hochrein, Evelin Weiss, Roland Dudek, Uwe Martens -

Patent number: 9834472Abstract: A method of manufacturing glass ceramic articles such as glass ceramic plates for cooktops or fireplace windows is provided. The method facilitates the adjustment of a specific hue or a specific absorptivity of the glass ceramic in the visible spectral range. The method is based on the finding that the absorption of light by coloring agents which are appropriate for or present in glass ceramics can be attenuated during the ceramization process by adding substances that have a decoloring effect.Type: GrantFiled: December 29, 2014Date of Patent: December 5, 2017Assignee: SCHOTT AGInventors: Falk Gabel, Friedrich Siebers, Ulrich Schiffner, Evelin Weiss
