The thermal shock resistance and anti-aluminum erosion of TiB2-BN multiphase ceramics com posites were studied. The experimental results show that the TiB2-BN multiphase ceramic possesses a good thermal shock resistance at high temperatures ( 1000,1200,1400,1500 ℃ ), with the increasing in thermal shocking tem perature, the electro-conductivity of TiB2-BN ceramics increases. The metal aluminum has a great influence on the properties of TiB2- BN ceramics and the main reason is that the aluminum reacts seriously with BN. It is suggested that the content of BN should be reduced to the greatest extent.
