Porous Nitride Ceramic Composites with Low-Dielectric Properties

Year: 2012

Type: article

Abstract: The influences of the mullite hollow balls content on selected properties of Si3N4-BN matrix ceramics were investigated.The experiment showed that the apparent densities and the porosity of the nitride ceramic composites decreased as the mullite hollow balls contents increased.The strength of the porous nitride ceramic composite was greatly improved, and the dielectric constant decreased with a small addition of the mullite hollow balls. SEM micrographs showed that the mullite hollow balls became one flesh with the nitride ceramic composites.Many large pores appeared in the whole materials. The properties of the nitride ceramic composites were effectively improved.
