A polyferrocarbosilane(PFCS) was synthesized from low molecular weight polysilane and ferrecene．The synthesis techniques including reaction temperature

pyrolysis temperature and ferrocene content were investigated．The molecular weight and soft point of PFCS increase with raising reaction temperature

pyrolysis temperature

and adding more ferrocene．The most suitable synthesis conditions for PFCS ale as follows

reaction temperature 350-420℃．pyrolysis temperature 450～510℃．The reaction temperature and pyrolysis temperature decrease greatly because of adding ferrocene．PFCS was charactefized by element analysis

FT-IR and 1H-NMR．As a result

element iron was inducted to the polymer

and it seemed that the structure of PFCS is similar to that of colycarbosilane (PCS)．The silicon carbide ceramic obtained from PFCS shows some magnetic properties．
