A kind of normal temperature and pressure synthetic method of Zr-Si-C ceramic precursor

The present invention is a kind of normal temperature and pressure synthetic method of Zr-Si-C ceramic precursor; the following steps are included: (1) is under inert atmosphere protection; dimethyl zirconocene is dissolved in organic solvent, organo-lithium compound, ligand compound are stirred and be added, is dried to obtain active zirconocene lithium salts；(2) under inert gas atmosphere protection, active zirconocene lithium salts is dissolved with organic solvent, stirs and halogenated silanes monomer is added; polymerization reaction occurs; terminator is added dropwise and terminates reaction, arrives Zr-Si-C ceramic precursor through filtering, concentration, purifying, drying.The method of the present invention is without conditions such as high temperature, low temperature, high pressure, energizations, it can be reacted at normal temperatures and pressures, using active high dimethyl zirconocene, relatively inexpensive and safer n-BuLi and halosilanes monomer reaction, Zr-Si-C ceramic precursor is prepared by two-step method, method is easy, scientific and reasonable.The Zr-Si-C ceramic precursor synthesized using this method is varied, can be used for preparing miscellaneous Zr-Si-C ceramics.
