Publication number: 20190321147Abstract: A method for manufacturing a shaped body, comprising creating a mixture of a metal powder and binding agent, compacting the mixture to form a green compact, heating the green compact to a debinding start temperature T1, debinding the green compact by controlled heating of the green compact from start temperature T1 to end temperature T2 at a heat-up rate R1, presintering the debindered green compact to the presinter end temperature TVS at a heat-up rate RHVS, cooling the green compact from the presinter end temperature TVS at a cool-down rate RKVS, whereby at least the heat-up rate RHVS, the presinter end temperature TVS, and the cool-down rate RKVS are tuned relative to each other in such a way that the presintered green compact forming a blank has a surface porosity of 16% to 22% after presintering, and machining and sintering of the blank to form the shaped body.Type: ApplicationFiled: June 26, 2019Publication date: October 24, 2019Applicant: DEGUDENT GMBHInventors: Jörg HACHENBERG, Rudi STEINKE, Markus VOLLMANN, Irmgard WISSEL, Gerhard ZELLMANN, Elmar HOCK, Stefan FECHER, Lothar VÖLKL

Patent number: 9321104Abstract: The invention relates to a device (10) and a method for sintering sinter products, such as oxidation-prone materials, in particular metallic sintered goods (46), in particular a dental framework, comprising a tray (18), which accommodates the sinter product and is arranged on a base plate (14), a pot-shaped cover (16), which surrounds the tray, with a rim (36) that is sealed towards the base plate, as well as supply and discharge openings (38) for protective gas connected to the interior chamber (30) that is surrounded by the pot-shaped cover. In order to facilitate sintering even at temperatures above 1200° C. without any problems, it is suggested that the tray (18) be covered by a capping element (20), whereby when the tray is covered by the capping element, the interior chamber (34) of the tray is connected in a gas-flow-allowing manner to the interior chamber of the cover.Type: GrantFiled: December 10, 2012Date of Patent: April 26, 2016Assignee: DEGUDENT GMBHInventors: Joerg Hachenberg, Rudi Steinke, Peter Popp, Irmgard Wissel

Publication number: 20160008233Abstract: A palladium-dominated dental alloy, in particular a ceramic-bonding dental alloy for the manufacture of dental prostheses such as crowns, bridges, inlays, or onlays, containing at least gold, palladium, and silver, as well as a grain-growth inhibitor in the form of ruthenium. In order to achieve a fine-grained separation without the formation of agglomerates to obtain a dental alloy with high mechanical stability and excellent polishing characteristics, it is proposed that the dental alloy contain—in addition to ruthenium as grain-growth inhibitor—at least one element of the group tantalum, niobium, yttrium, zirconium, chromium, and molybdenum as grain-refinement control element.Type: ApplicationFiled: September 25, 2015Publication date: January 14, 2016Inventors: Joerg HACHENBERG, Rudi STEINKE, Angela KLAUS, Irmgard WISSEL
