Enhanced microwave absorption properties of polymer-derived SiC/SiCN composite ceramics modified by TiC

“…Thirdly, a large number of nanophases precipitated from the matrix, including nanocrystalline SiC, TiC, graphite and SiC nanowires in the pores, are easy to form local conductive networks in matrix. Induced microcurrent caused by electromagnetic wave conducts in the networks, converting electromagnetic energy into heat energy to form conductivity loss [40]. Moreover, SiC nanowires are also an important factor in electromagnetic wave loss.…”
