Playing with Self-Igniting Gases: Silane, Phosphine, and Borane | Pyrophoric Chemistry

Ғылым және технология

They say you shouldn't play with fire, so I did the next best thing: I played with gases that light THEMSELVES on fire!
There are several excellent videos already published that show pyrophoric gases to varying degrees. For example, Explosions&Fire covered silane and diborane, ChemicalForce did phosphine and diborane....even Thy Labs tried silane a while ago, so I think it's about time I joined the pyrophoric club!

    With magnesium silicide/silane, it's more fun (imo) to use water to get the product. You can break the test tube containing the Mg2Si and drop the solid chunks into water. They react to form bubbles of SiH4, which then burst into flame when they pop on the surface. If it doesn't want to make nice bubbles you can add a little bit of soap. It's a lot more controlled than adding acid, so you get to see the reaction more clearly and it goes several times. As a fun side effect, you can actually see the SiO2 (sand) that is the other product of the combustion as it forms on the surface of the water.

    This is why chemistry is so magical; you literally just created a "fire potion" like some kind of STEM wizard. Quick question though, at 4:03 you mention diborane having a weird Swedish odor. I've never actually been to Sweden so I don't what it smells like there, but would Swedish fish odor be comparable in scent?

One happy accident is the valve that added the trimethyl aluminum fired a couple extra shots in the chamber and we rolled with it. The result was 614nm orange laser chips with a safe operating power of 250mW.

    I suppose I could superheat calcium phosphate with charcoal in a kiln to get the phosphorus needed to make phosphine, but making silane from silicates wouldn't make much sense, since silicon dioxide (sand) is fair more abundant. Likewise, I could make the sodium borohydride myself from boron trioxide, but that would require access to sodium hydride and methanol, so ultimately, buying sodium borohydride directly makes the most sense.

    Most of these gases do find some uses (silane in the semiconductor industry, phosphine as an animal poison, etc), but uses involving their pyrophoric properties are limited. NASA uses stuff like diborane to ignite their rocket engines during takeoff, but besides that there isn't much...might be cool to use in a weapon though!
