摘要： The invention relates to a method for producing two-membered or multi-membered all-ceramic dental shaped parts such as bridge substructure elements and the like. According to the method, a model is firstly produced from the basic structure, for which the dental shaped part is provided. By using this model and a suspension of ceramic particles, a ceramic base body is formed, in particular by means of electrophoretic deposition, and is subsequently sintered. The method provides that the dimensions of the model are, at least in part, selected in order to compensate for shrinkage resulting from the sintering of the base body whereby achieving, in this manner, the desired fit between the dental shaped part and the basic structure.

摘要： The invention relates to a dental moulded part which can be produced from ceramic particles by firing the green product obtained therefrom. The structure of said moulded part contains ceramic fibres and/or nanocrystalline particles. The invention also relates to a method for producing a ceramic moulded part for dental use. According to the inventive method, the ceramic particles dispersed in a liquid dispersion agent are electrophoretically separated from the dispersion on an electrode corresponding to the form of a dental base body. The ceramic particles are made partially from ceramic fibres and/or nanocrystalline particles.

摘要： In a method for treating waste materials containing nitrite, the nitrite is oxidized to form nitrate in the presence of acid using at least one oxidant containing manganese(IV) or manganese(VII). The acid can be provided by waste acid, preferably waste acid containing nitric acid. The oxidant, which is preferably manganese dioxide, can also originate from waste materials, for example, from battery production. The invention relates to a nitrogen-containing concentrate, which contains preferably at least 2 wt% nitrogen, preferably at least 4 wt% nitrogen. Said concentrate can be employed and utilized in agriculture or in horticulture as a fertilizer.

摘要： The invention relates to a machine tool for machining a workpiece, comprising a fixed frame, a workpiece hopper (50) and a workpiece carriage (50) movable with respect to the frame for receiving a workpiece (36a-36l), wherein said workpiece hopper (50) is designed to receive a plurality of workpieces (36a-36l), wherein said workpiece hopper (50) is designed to move workpieces (36a-36l) into a transfer position (70), and wherein said workpiece carriage (30) is designed for the translative movement of said workpiece (36a-36l) in the course of workpiece machining in the direction of an X-axis. According to the invention, the workpiece carriage (30) can be moved in the direction of the X-axis far enough that the workpiece (36a-36l) received on said workpiece carriage (30) can be moved into the transfer position (70). The invention can be used in particular for machine tools for producing dental prosthetics or denture models.
