Aluminothermic combustion of “Al-metal oxide” blends compacted in the presence of silica sol added as a binder was found to proceed at lower combustion temperatures and burning velocities as compared to those in the absence of sol. The results show that the addition of silica sols to green mixtures can be used as an effective approach to performing aluminothermic SHS reactions yielding new refractory composite materials at moderate temperatures of 1000–1600dgC.
