“…In sample OSR, 2968 cm −1 is the C‐H stretching vibration absorption peak of Si–CH 3 29 . The absorption peaks at around 1000 cm −1 correspond to the typical stretching vibration peaks of Si–O–Si, 30 which is close to the characteristic stretching vibration of [SiO 4 ] structure. The absorption peak at 1061.84 cm −1 is 30 cm −1 lower than the typical peak of Si–O–Si in the [SiO 4 ] structure at 1090 cm −1 .…”

A route preparing SiOC/SiC nanocomposites directly by pyrolysis of organosilane slurry residue was investigated. Organosilane slurry residue's unique composition, containing both silicon and carbon, offers an intriguing platform for developing advanced ceramic materials. The pyrolysis process is examined comprehensively, revealing the chemical reactions and structural changes leading to SiC crystals formation. The phase evolution at various annealing temperatures was revealed. Crystallization behavior in the process were studied. The results reveal that SiOC matrix was generated at annealed temperature 800°C and SiC nanoparticles were formed at 1300°C. In comparison to phase separation of SiOC, carbothermal reduction of SiO2 was domain in SiC formation. This research advances the understanding of SiOC/SiC nanocomposites, highlighting the value of repurposing industrial byproducts for sustainable and innovative materials development.
