Reactivity Profile
MAGNESIUM CHLORATE is a powerful oxidizer. Explosive reaction with copper(I) sulfide. Incandescent reaction with antimony(III) sulfide, arsenic(III) sulfide, tin(II) sulfide, tin(IV) sulfide. Incompatible with Al, As, C, Cu, MnO2, organic matter, organic acids, P and S. [Lewis, 3rd Ed. 786]. Mixtures with ammonium salts, with powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979. p. 806]. A combination of finely divided aluminum and magnesium chlorate can explode by heat, percussion, or friction [Mellor 2:310. 1946-47].
