Polycarbosilane powder, formed by a desaturation process, was oxidation-cured at 180–340°C and pyrolyzed in a hydrogen atmosphere to obtain Si–O–C(–H) ceramics with low carbon contents. FT-IR was used to investigate the progress of the oxidation curing. Suitable curing conditions were found to be 240°C for 20h, and the powders obtained after the pyrolysis exhibited intense luminescence under UV irradiation...
