Abstract: A method for the production of blanks for sintered glass bodies for glass seals, wherein with a 3D printing method, a number of layers are arranged one above the other. In a first step, a first layer of a glass powder is spread on a surface, a computer-controlled stream of a printing fluid is directed to selected areas of the first layer in a pattern prescribed by the computer. In a second step, a further layer of the glass powder is spread over the first layer and on it, a computer-controlled stream of printing fluid is directed to selected surfaces of the second layer in a pattern prescribed by the computer, the two steps are repeated until the blank is formed. The glass powder components contain SiO2, Na2O, K2O, CaO, MgO, B2O3, BaO, Al2O3, PbO, Li2O and SrO as well as a solid binder made of dextrin.

Abstract: Contact pins for glass seals is provided having an iron alloy and a method for their production. The contact pins are provided with a nickel layer and coated with rhodium and/or platinum or with palladium. The contact pins may be additionally provided with a layer of gold. The contact pins are first cleaned by degreasing and activating, preferably by activating through acid etching. Thereafter, the application of a nickel layer is performed under a protective gas atmosphere, followed by formatting at 850 to 1050° C. The protective gas atmosphere is preferably made up of 10 to 100% hydrogen, with the balance formed of nitrogen. This is followed by a coating with palladium or with rhodium and platinum, or with platinum, or with rhodium and gold.
