  • Patent number: 10501363
    Abstract: A method for production of a photo-structurable glass element is provided. The method includes the steps of: fixing a blank of photo-structurable glass at a first end; heating of a deformation zone of the blank; and drawing the blank. The glass includes Si4+, a crystal-agonist, a crystal-antagonist, and a pair of nucleating agents. The crystal-agonist is selected from the group consisting of Na+, K+, Li+, and any combinations thereof. The crystal-antagonist is selected from the group consisting of Al3+, B3+, Zn2+, Sr2+, Sb3+, and any combinations thereof. The pair of nucleating agents include cerium and an agent selected from the group consisting of silver, gold, copper, and any combinations thereof. The crystal-agonist has a molar proportion cat.-% in relation to a molar proportion of Si4+ that is at least 0.3 and at most 0.85.

  • Patent number: 10472273
    Abstract: A sensitized, photo-structurable glasses and methods for producing are provided. The glasses includes Si4+, one or more crystal-agonist, one or more crystal-antagonist, and one or more pair of nucleating agents. The glasses are sensitized in that the glass reacts more sensitive to irradiation with UV-light and can be crystallized easier and with higher aspect ratios than a non-sensitized glass with equal composition. Furthermore, the sensitized glasses of this invention have smaller crystal sizes after irradiation and tempering than a non-sensitized glass with equal composition. The invention also relates to a structured glass product. Such product can be obtained by submitting the crystallized glass product to a subsequent etching step. The structured product can be used in components or as component for the application fields micro-technology, micro-reaction-technology, electronic packaging, micro-fluidics, FED spacer, bio-technology, interposer, and/or three-dimensional structured antennae.

  • Patent number: 10207948
    Abstract: The present invention relates to an improved cordierite glass-ceramic. In order to improve the materials properties, it is proposed that the glass-ceramic comprising SiO2, Al2O3, MgO and Li2O contains cordierite as main crystal phase and that a secondary crystal phase of the glass-ceramic comprises high-quartz solid solution and/or keatite solid solution. The invention further relates to a process for producing such a glass-ceramic and the use of such a glass-ceramic.

  • Patent number: 10106454
    Abstract: The present invention relates to optical glasses, in particular special short flint glasses (KZFS) and optical elements and components, which comprise these glasses, and use thereof and a method for producing such optical glasses. The optical glasses of the present invention are characterized by a pronounced short flint character and additionally by an excellent transmission and chemical resistance and workability. At that, the glasses of the invention can stand out due to lower costs of production caused by lower costs of raw materials and lower processing costs, due to their crystallization properties that can be handled also in smaller melting aggregates, and due to good environmental compatibility.

  • Patent number: 10093575
    Abstract: A method for continuous production of photo-sensitive glass bodies, glass bodies, and structured glass articles are provided. The glass bodies include a glass having Si4+, at least one crystal-agonist, at least one crystal-antagonist, and at least one pair of nucleating agents. The glass may be used in a method for structuring of glass. The glass bodies may be structured and/or unstructured and used in different applications such as in components or as components in micro-technology, in micro-reaction-technology, in electronic packaging, for micro-fluidic components, in or as FED spacer, for bio-technology (for example titer plates), as interposer, and in or as three-dimensional structurable antennae.
