Dense SiC-AlN solid solution ceramics with 0-15wt%AlN were fabricated by pressureless solid state sintering with B4C/C as sintering additives.The samples were sintered at 2160 ℃ for 30min and then annealed at 1950 ℃ for 60min with protective powder.The effect of AlN content on the relative densities,thermal conductivities of composites were investigated.
