SUMMARY Compact silicone/alumina composite was obtained by highly filling aluminum oxides and hydroxides in silicone resin. The flexural strength and dimensional change of the silicone/alumina composite after being fired has have been studied. It presented a special fire resistance, which could well coordinate the contradiction between the mechanical strength retention and the dimensional stability of silicone‐based composite in case of catching fire. Thermogravimetric analysis, scanning electron microscopy, X‐ray diffraction, transmission electron microscopy, and electron dispersion spectroscopy were applied to systematically explore the process of the in‐suit organic‐to‐inorganic transformation. A possible mechanism was proposed to illustrate the phenomenon of the high strength retention and dimensional stability of silicone/alumina composite under fire.
