Low Temperature Sintering of AIN-SiC-TiB2 System for the Fabrication of Continuous Fiber Reinforced Ceramic Composites (CFCC)

摘要

We report sintering additive systems to decrease the densification temperature of the corrosion resistant AIN-SiC-TiBi system. Since oxide additives degrade the high temperature properties of the system, and other kinds of metallic additives may affect the formation of protective mullite during oxidation, only the constituent elements were applied as additives. Dense samples ( > 98 % relative density) could be fabricated at 1850℃ and 1900℃ by spark plasma sintering (SPS) and hot pressing method, respectively.
