摘要：
Metal-containing (Mn, Fe, Co, Cu, Zn and Ag) polysilazane precursors are synthesized via one-step chemical reaction of metal acetates with poly(vinyl)silazane (Durazane 1800) at room temperature under argon atmosphere. The ATR-FTIR spectra of the synthesized metal-containing precursors reveal that the metal acetates used in the synthesis catalyze the hydrosilylation reaction between -Si-H and-Si-CH--CH2 groups in polysilazane. The XPS and XRD characterizations indicate that the metallic phase is directly generated in precursors after the reaction of Durazane 1800 polymer with Fe(CH3COO)2, Co(CH3COO)2 & sdot;4H2O, CuCH3COO, Cu(CH3COO)2, AgCH3COO. Ceramic nanocomposites containing either metal or metal silicide are obtained after the pyrolysis of the synthesized metal-containing precursors at 700 degrees C and 1100 degrees C under argon atmosphere.
