One thing it holds over magnisium though, is that burning magnisium doesn't like water, it really doesn't like water. Zirconium powder has a lower combustion temperature then magnesium so the reaction shouldn't be as bad. If you want to see how it reacts with fire, magnesium fire

It's not that it reacts badly with water; it burns so hot that the water in the video was spreading the powder around and the magnesium was catching fire and blazing up.
You can't put magnesium out with water I've watched magnesium flares burn under water.
