ABSTRACT OF THE DISCLOSURE A silicone composition cures to a flame retardant silicone elastomer by heating. The composition contains 100 parts by weight of vinyl-containing polydiorganosiloxane fluid with a viscosity of 0.2 to 30 Pa?s at 25°C., an organohydrogensiloxane in an amount sufficient to provide from 1.2 to 3 silicon-bonded hydrogen atoms for every silicon-bonded vinyl group in the composition, from 5 to 100 parts by weight of reinforcing silica filler, a platinum catalyst providing at least 1 part by weight of platinum for every one million parts by weight of polydiorganosiloxane fluid, and from 0.1 to 3 parts of ceric hydrate. The flame retardant silicone composition is useful for potting, encapsulating, molding and extruding processes.
