Abstract

Dense ceramic composite material (AlN–hВN) / (TiB₂–TiAl₃) has been prepared by hot pressing; its electrical and thermal conductivity for a range of conductive phase content were measured. Charge transfer mechanism in as-obtained material of the dielectric matrix / conductive inclusions system is discussed.
