Technique of joining of C_f/SiC composite via preceramic silicone polysilazane and joining properties;

Preparation of SiO_2-containing coatings of polysilazane via UV-curing;

Study on crosslinking of polycarbosilane/polysilazane precursor system;

When methylchlorosilanes and phenylchlorosilane were ammonolyzed with ammonia gas, various polysilazanes were produced which could be typically pyrolyzed at high temperature and subsequently ground into Si-C-N ceramic powders.

Polysilazanes can be used as precursors to prepare silicon\|nitride ceramics by pyrolysis.

The pyrolytic process of three kinds of preceramic polymers,polysilazane(PSZ),polysiloxane(PSO) and polycarbosilane(PCS),were investigeted.

Performance of polyborosilazane and SiBNC ceramics thereof;

Characterization and Rheological Property of Polyborosilazane

New preceramic polymers-hybrid polyborosilazanes(H-PBSZ)were synthesized and char- acterized.

Preparation of Hyperbranched Polycarbosilazane via Ultraviolet Initiated Hydrosilylation;

Polycarbosilane which contains alkynyl groups in main chain,including PCS containing alkynyl only,alkynyl and aromatic ring,alkynyl and metal elements,polycarbosiloxane and polycarbosilazane is reviewed.

Polyvinylsilazane (PVSZ) is a well known ceramic precursor for the fabrication of high performance ceramic structures which are involved in harsh environments.
