N2 - The application of Ti powder as active filler in the ceramic preparation by polysilazane (PSN-1) precursor pyrolysis was researched by means of IR, TG and XRD. Results show that Ti powder can effectively improve the ceramic yield of the precursor. In the experiment, the ceramic yield of the pure PSN-1 precursor pyrolyzed at 1300°C was only 37.3%; while after adding Ti powder (Ti/PSN-1=3/10, mass fraction), the yield after 1300°C pyrolysis was 78.7%, increasing by 40%. IR spectra reveal Ti powder addition to the precursor can accelerate the transformation from organic precursor to inorganic ceramic. XRD analysis show Ti powder as an active filler in the precursor can react with the cracker-volatile and the protective atmosphere, generating TiC, TiN and other new phases, which favors the increase of the ceramic yield.
