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 DEG 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.
