An organic/inorganic composite phenolic resin ( CPR ) was synthesized via silicon particles in situ composite with water‐soluble lignin–phenolic resin. It was observed that silicon particles were uniformly dispersed in the organic matrix. The oxidation activation energies of the pyrolytic products from CPR and commercial phenol formaldehyde resin ( PF ) were calculated as 173.3 kJ /mol and 102.4 kJ /mol, respectively, by nonisothermal kinetics method. Dumbbell‐shaped silicon carbide nanowires were formed on the surface of the pyrolytic carbon from CPR at high temperature. The oxidation resistance and mechanical properties of the Al 2 O 3 ‐C refractories bonded with CPR were improved.
