POROUS MOLDED BODIES FROM POLYCRYSTALLINE SILICON NITRIDE AND METHOD FOR PRODUCING THE SAME

摘要

The invention relates to a method for producing porous molded bodies on the basis of silicon nitride. According to the inventive method, a batch of a silicon nitride powder that has a modal particle size distribution of coarse and fine particles is precompacted to form a green compact and is baked using a temperature-based sintering process.
