Abstract: The invention relates to a thermal element comprising a shaft and a test prod arranged on one end of the shaft. The thermal element comprises a first conductor and a second conductor, which are manufactured from different conductor materials and which are in electrical contact on one contact point provided in the region of the test prod. The first conductor and the second conductor are embedded at least in sections in a material of the shaft. The contact point is additionally or alternatively to the shaft material shielded with respect to the outside space at least in sections by means of a shield formed by a shielding material, wherein the shielding material has a lower diffusion coefficient and/or a higher thermal conductivity than the shaft material.

Abstract: The invention relates to a press furnace for a denture or partial denture, having a combustion chamber in which a press mold, in particular a muffle, having a press channel for the introduction of a ram can be positioned, and a drive for driving the ram, wherein, in order to improve the drive of the press furnace, the drive provided is an electromagnet, the magnetic armature or magnetic coil of which drives the ram.

Abstract: A firing tray for a furnace for dental ceramics having a plate for the placement on it of the firing material, wherein the plate is made as a base for the improvement of the application possibilities and the firing tray has additional wall elements which are designed for the placement on them of a further firing tray for the forming of a stack.

Abstract: The invention relates to a furnace for a dental prosthesis, or a partial dental prosthesis, comprising a furnace chamber, a plurality of heating elements for heating the furnace chamber, and a power connector for connecting the heating elements to a power grid, wherein means for limiting the power consumption of the furnace are provided in order to increase the application possibilities and improve the furnace performance.

Abstract: The invention relates to a firing furnace for a tooth replacement or tooth prosthesis, with a firing chamber, at least one heating element for heating the firing chamber, a control unit for controlling the operation of the firing furnace, and a housing at least partially surrounding the firing chamber, wherein the firing furnace comprises at least one thermoelectric element for utilizing the waste heat generated by the firing furnace.

Abstract: A firing aid, in particular for supporting material to be fired in a furnace during filing, is obtainable by a method including the following steps: a) providing a mixture of at least 60% by weight mullite powder which comprises 74.0 to 78.0% by weight Al2O3, 22.0 to 26% by weight SiO2 and a maximum of 0.5% contaminants, with the sum of the Al2O3 content and of the SiO2 content amounting to at least 99.5% by weight; 1 to 20% by weight binder; 0 to 20% by weight plasticizer; and remainder to 100% by weight of one or more additives; b) pressing the mixture provided in step a) to a green body; and c) sintering the green body.

Abstract: The invention relates to a stove for producing denture and or the parts thereof comprising a combustion chamber and a heating device which is arranged therein and provided with a heating spiral consisting of an appropriate resistance wire and a support for the heating spiral. The aim of said invention is to better use the heating energy and make it possible to easily replace the heating device. For this purpose, the heating spiral is arranged on the external part of the support.
