Abstract: A glass includes cations of the following components in the indicated amounts (molar proportion in cat.-%): 30-80 cat.-% silicon; 0-20 cat.-% boron; 0-2 cat.-% aluminum; 5-35 cat.-% sodium; 2-25 cat.-% potassium; 0-0.5 cat.-% nickel; 0-0.5 cat.-% chromium; and 0.03-0.5 cat.-% cobalt. A sum of the molar proportions of cations of sodium and potassium is in a range of from 15 to 50 cat.-%, a sum of the molar proportions of cations of nickel and chromium is in a range of from 0.1 to 0.5 cat.-%, and a ratio of the sum of the molar proportions of cations of sodium and potassium to the sum of the molar proportions of cations of nickel and chromium is in a range of from 70:1 to 200:1.

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.

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.

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.
