A polyferrocarbosilane( PFCS) was synthesized from polydimethylsilane ( PDMS) and ferrocene.
Nano-Fe3Si/ SiC composite ceramic absorbent can be obtained by pyrolyzing PFCS. It was systematically studied that electromagnetic parameter of absorbents was affected by some factors,for example,ferrocene,sintering temperature and holding time and so on. The results show 、and rincrease greatly by adding more ferrocene,raising sintering temperature and prolonging holding time.
