Abstract
The nano SiC(N) powder was synthesized by laser-induced gas-phase reaction. SiC(N)/LAS nano-composite was prepared from LAS glass powder and as-formed nano SiC(N) powder by the hot-pressing method. The microwave dielectric properties of the SiC(N)/LAS nano-composite in a frequency range of 8.2-12.4 GHz were studied. The results show that the permittivity of the nano-composite is related closely to the content of nano SiC(N) and influenced fairly by sintering temperature. Compared with the mixture of nano SiC(N) and paraffin, the sintering process improved the SiC(N)/LAS nanocomposite's dissipation to the electromagnetic wave. The amelioration is ascribed to the formation of the carbon interface between nano SiC(N) and LAS matrix.
