Abstract
We have studied and summarized data on structure formation and dielectric c haracteristics of Si3N4-based materials obtained by hot pressing and activa ted sintering. We have measured the dielectric characteristics in the frequ ency range I kHz to 10 MHz. We have established that the level of the diele ctric characteristics of the materials is significantly affected by the con tent of highly dispersed Si3N4 powder obtained by plasmochemical synthesis in the original mix.
