Preparation and Dielectric Properties of Si3N4/BN(CB) Composite Ceramic

High Temperature Materials and Processes, 2016
Si3N4/nano-carbon black (CB) composite ceramics with boron nitride (BN) as interphase were fabricated by gelcasting. The results of scanning electron microscopy (SEM) and X-ray diffraction (XRD) showed that the structures of BN interphase and BN coated ...
