摘要： A dental sintering furnace for sintering ceramic dental elements comprises a receiving chamber (10) for receiving the dental element (14) to be sintered. The receiving chamber (10) is surrounded by an electric heating unit (24) for heating the dental elements (14) to a pre-sintering temperature. Further, the receiving chamber (10) is surrounded by an annular microwave conductor (30) designed as a hollow conductor. On an inner wall (46), the microwave conductor comprises a plurality of decoupling slots (48) to decouple the microwaves in the direction of the receiving chamber (10). In a method for sintering ceramic dental elements, all the dental elements are first heated to a pre-sintering temperature by means of the electrical heating unit (24) and then the dental elements (14) heated to the pre-sintering temperature are irradiated by microwave radiation for coupled heating of the dental elements (14) to the sintering temperature.

摘要： The invention relates to a microwave heater comprising a plurality of microwave generators each emitting microwaves at a frequency in a range of frequencies ranging from 300 MHz to 5.8 GHz which couple into objects to be heated. At least one of the microwave generators emits the microwaves at a first frequency of an upper part of the range of frequencies, the microwaves of the first frequency displaying a first of depth of penetration into the objects to be heated; and at least one other of the microwave generators emits the microwaves at a second frequency of a lower part of the range of frequencies, the microwaves of the second frequency displaying a second depth of penetration into the objects to be heated, the first penetration depth being substantially smaller than the second penetration depth.
