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 Si, 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 Al, B, Zn, Sr, Sb, 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 Sithat is at least 0.3 and at most 0.85.

Method for producing photo-structurable glass bodies by a redrawing method

A sensitized, photo-structurable glasses and methods for producing are provided. The glasses includes Si, 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.

Sensitized, photo-sensitive glass and its production

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 Si, 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.
