    摘要: The invention relates to a method for continuously producing pre-ceramic polymers. The inventive method consists in synthesizing polymers, in separating polymers from a reaction mixture and in thermally conditioning for defining a cross linkage degree and rheological properties, wherein all said steps are integrated into a single method. The thus obtainable polymers are used in the form of an initial material for producing non-oxidized ceramics in ternary X/Y/N or X/Y/N/C quaternary systems. Said materials are characterized by the high mechanical, thermal and chemical resistance thereof, wherein any X and Y combination can represent in particular Si, B, P, Al, Ti, V, Zr, Ta elements.

    摘要: The invention relates to a new class of luminescent substances (phosphorous) based on an universally dopable matrix made of an amorphous, at the most partially crystalline network of the elements P, Si, B, Al and N, preferably the composition Si3B3N7. Optical excitation and emission can be varied in this system over the entire practically relevant field by incorporation of any cationic activators, alone or in combination, but also by incorporation of oxygen as anionic component. This opens up the entire spectrum of use of luminescent substances, such as illumination systems or electronic screens.
