    Abstract: The invention relates to a sintering furnace (1) for components (15) made of a sintered material, in particular for dental components, comprising a furnace chamber (2) having a chamber volume (VK) and a chamber inner surface (OK), wherein a heat-up device (5), a receiving space (9) having a gross volume (VB) located in the chamber volume (VK) and delimited by the heat-up device (5), and a useful region (10) having a useful volume (VN) located in the gross volume (VB), are disposed in the furnace chamber (2). The furnace chamber (2) has an outer wall (3) consisting of a plurality of walls having a wall portion (7) to be opened for introduction into the receiving space (9) of a component to be sintered (15) and having an object volume (VO). In the furnace chamber (2) the heat-up device (5) has a thermal radiator (6) having a radiation field (13) which radiator is disposed on at least one side of the receiving space (9). Said thermal radiator (6) has a specific resistance of 0.1 Ωmm2/m to 1,000,000 Ωmm2/m and has a total surface, the maximum of which is three times the chamber inner surface (OK). With this sintering furnace (1) a heat-up temperature of at least 1100° C. can be achieved within 5 minutes at a maximum power input of 1.5 kW.

    Abstract: An electrical heater has first and second heater elements, each having a hairpin-shaped metal tube with an upstream and a downstream leg and tube ends adjacent each other. An electrical resistance wire surrounded by insulation powder extends through the tube. Electrical terminals join to the wire and protrude from each of the tube ends. Conduits enclose the upstream and the downstream legs of the heater elements, providing a continuous annular flow path. A manifold has heater element passages for end portion of the legs. An inlet passage in the manifold leads from an exterior portion of the manifold to the annular flow path surrounding the upstream leg of the first heater element. A transfer passage within the manifold leads from the annular flow path surrounding the downstream leg of the first heater element to the annular flow path surrounding the upstream leg of the second heater element.
