| Abstract: | AlN-TiN-TiB2 composite conductive ceramics from powder mixtures of Al,TiN,B4C and Si were fabricated by self-propagating high temperature synthesis (SHS) and hot isostatic pressing (HIP). The compositions and morphologies of the combustion product were studied by XRD and SEM. The fracture mode of SHS/HIP sintered AlN-TiN-TiB2 composite conductive ceramics belongs to brittle intercrystalline fracture. The temperature-dependence and composition-dependence of the electrical resistivity of AlN-TiN-TiB2 ceramics... |
