Abstract :
The microstructure and resistivity of AlN/BN ceramic nano-composites and micro-composites were investigated. The results showed that because the nano-BN crystals were homogeneously dispersed around the AlN grains of the matrix, the conductive glass phase surround AlN grains were separated, and the it was difficult to form the electric conductible consecutive passageway (than micro composites), the leakage conductance of nano-composites was far lower than micro-composites.
