Abstract: The invention concerns a microwave oven (10) for the heat treatment of ceramic components, in particular of dental ceramic components (12). It is equipped with a susceptor (14) which is positioned in the swell or in the area between a source of microwaves and the component. The susceptor (14) is made of highly pure silicon carbide of hexagonal, rhombohedral or cubic crystal structure, which has in particular a 2H, 4H, 6H or 3C crystal structure.

Abstract: This invention relates to a device for heating moldings, in particular dental ceramic moldings with the aid of a microwave generator that impinges a susceptor with microwave radiation, said susceptor being arranged between the molding and the microwave generator. Preferably, the susceptor at least partially forms both an inner ring and an outer ring, and the molding is arranged between the inner ring and the outer ring.

Abstract: A furnace for the thermal treatment of at least one dental firing object, comprising a housing, a firing chamber, a firing chamber base, a heating device, and at least one optical temperature detection element which can be used to detect a temperature in the firing chamber and is intended to enable a contactless temperature measurement of a dental firing object in a simple manner. This is achieved by virtue of the fact that the firing object is mounted on and/or in and/or below and/or alongside a firing aid situated in the firing chamber, and the optical temperature detection element detects the temperature of the firing aid.
