Shock Resistance

The influences of hexagonal BN content on the porous Si3N4 material was investigated. SEM micrographs showed that the columnar crystal overlapping structure of the porous Si3N4 material with a small BN addition was almost invariant. BN uniformly dispersed in the spaces of crystal overlapping. The experiment showed that the apparent densities of the porous Si3N4 material with a small BN addition marginally increased, the porosity, the strength and the dielectric constant marginally decreased, but The thermal shock resistance was greatly improved.
