摘要： 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.
摘要翻译：本发明涉及一种用于烧结烧结产品的装置（10）和烧结产品，例如氧化易发生材料，特别是金属烧结制品（46），特别是牙科框架，包括托盘（18），其容纳烧结体产品并且布置在基板（14）上，围绕托盘的盆形盖（16）具有朝向基板密封的边缘（36）以及供给和排出开口（38），用于保护气体连接到由罐形盖包围的内部腔室（30）。为了便于在高于1200℃的温度下的烧结，没有任何问题，建议托盘（18）被封盖元件（20）覆盖，由此当托盘被封盖元件覆盖时，内部室托盘的内部（34）以允许气体的方式连接到盖的内部室。

摘要： 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.

摘要： 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.
