Catalytic Properties of ZrB2-based Ultra-high Temperature Ceramics based on the Wall Temperature Response Method
This paper presented the application of microwave-discharge plasma apparatus which was used to evaluate the catalytic properties of ZrB2-based ultra-high temperature ceramics in the simulated real service environment by the wall temperature response method based on the heat balance principle.The results showed that the material composition had a significant influence on the catalytic properties of ZrB2-based ultra-high temperature ceramics,and the catalytic activity of ZrB2-SiC composites with Cr addition had been increased significantly.The relationship between catalytic properties of ZrB2-based ultra-high temperature ceramics and surface composition was discussed in detail.The composition optimization was considered to be a very effective way to inhibit the recombination reactions of dissociated atoms on the surface of ultra-high temperature ceramics.
