Preparation of Highly Porous Silicon Nitride Materials

Аннотация

A short review is given of existing methods for preparing highly porous silicon nitride materials. The possibilities of a method described are based on consolidation of previously prepared elements from a thermoplastic slip with thixotropic rheological properties. Different combinations of thermal and mechanical action during element consolidation in the form of shavings may lead to different distribution of porosity throughout the volume of the objects prepared.
