    • SiGNa chemistry has developed three categories of alkali metal nanostructured silica materials (M-SG): Stage 0 materials are strongly reducing pyrophoric powders; Stage I materials are nonpyrophoric, free-flowing black powders with reactivity equivalent to neat alkali metals, and Stage II is less reducing but reacts with water to produce hydrogen at pressures from ambient to several thousand psi. All three categories of MSG, with different metals and metal alloys absorbed, are available commercially.

    • Although these M-SG(I) reagents do not react with dry air, they can degrade rapidly in ordinary moist lab atmospheres. Thus, appropriate caution should be exercised in handling these materials. Like the pure alkali metals, these materials react vigorously and exothermically with water, giving off flammable hydrogen gas.
