incombustible

If someone told me that incombustible and inflammable used to point at the same property at one point, I’d believe that.

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.

That said, the sooner Starship achieves full reusability, the sooner we'll stop burning rocket stages into the atmosphere and letting the incombustible parts fall into the ocean.

I don't remember the details, but on a previous article on wooden skyscapers, it was explained how the engineering of the wood, which is also required for the necessary structural strength, made it very dense and practically incombustible.

Ooh, that's fun: "The ability to surpass the oxidizing ability of oxygen leads to extreme corrosivity against oxide-containing materials often thought as incombustible.

Also pretty silly for " flammable "/" inflammable " to be synonyms when " combustible "/" incombustible " are antonyms.

However, for Lithium Iron Phosphate LiFePO4: "Lithium phosphate cells are incombustible in the event of mishandling during charge or discharge, they are more stable under overcharge or short circuit conditions and they can withstand high temperatures without decomposing."
