The thermal decomposition and crystallisation behaviour of boron containing siliconoxycarbide (SiCO) ceramics were studied. The samples were prepared by pyrolysis of SiO 2 /B 2 O 3 filled poly(dimethylsiloxanes) at 1300°C and subsequent annealing at T > 1300°C. TEM and XRD investigations show the formation of β‐SiC during annealing at 1300°C. The resulting material can be described as a borosilicate glass with homogeneously dispersed nano β‐SiC crystals.
