Abstract

Polyorganoborosilazanes with the limited B/Si/C ratios and with or without Si-H bonds were molecular-designed and synthesized. By pyrolysis of these polymers in Ar atmosphere, amorphous borosilicon carbonitrides stable at 1880°C were prepared. The amorphous structure of borosilicon carbonitride was related to the polymer structure.
