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.

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: 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.

Abstract: A method to produce a clear glass or a clear drawn glass includes the steps of melting starting materials to obtain a glass batch melt, refining the obtained glass batch melt, homogenizing the obtained glass batch melt, and producing a glass product in the drawing process. A sulfate refining agent, selected from an alkali-, alkaline earth- or zinc sulfate or mixtures thereof is utilized in a predetermined amount and a predefined refining temperature during refining of the glass batch melt which is 0° C. to 100° C. higher than that in a refining process using a refining system which contains antimony oxide on its own or in combination with one or several other refining agents.
