I’ve seen the blogpost before, but the Wikipedia article is great. From Wikipedia: > This oxidizing power, surpassing that of oxygen, causes ClF3 to react vigorously with many other materials often thought of as incombustible and refractory. […] In one particular industrial accident, a spill of 900 kg of ClF3 burned through 30 cm of concrete and 90 cm of gravel beneath. Two things: First, the idea of burning (not melting!) through 1.2m of what is effectively stone is wild. Second, somebody had 900kg of this stuff in one place?!
