✦ Synopsis

Nonoxide ceramics can be obtained from the high temperature pyrolysis of organometallicpolymerpre- cursors. This study has focused on the processing behavior of a commercially available polycarbosilane precursor, whereby the thermal and rheological behavior was investigated employing a Rheometrics mechanical spectrometer, RMS 800, and a Perkin-ABSTRACT Elmer Model 4 differential scanning calorimeter. The effects of various environments including nitrogen and oxygen were also studied. The melt processing capability of polycarbosilane was found to be rather limited. Finally, a model which describes the pore formution process during pyrolysis has been proposed.
