What does hafnium react with?
Hafnium makes a new substance with 10 other elements and chemicals in our lab:
- Hafnium + HydrogenHafnium hydride Hf + H₂ → HfH₂ · When heated · Try it
- Hafnium + BoronHafnium boride Hf + 2B → HfB₂ · Only in a very hot furnace · Try it
- Hafnium + CarbonHafnium carbide Hf + C → HfC · Only in a very hot furnace · Try it
- Hafnium + NitrogenHafnium nitride 2Hf + N₂ → 2HfN · Only when heated very strongly · Try it
- Hafnium + OxygenHafnium oxide Hf + O₂ → HfO₂ · When heated · Try it
- Hafnium + FluorineHafnium fluoride Hf + 2F₂ → HfF₄ · At room temperature · Try it
- Hafnium + SulfurHafnium sulfide Hf + 2S → HfS₂ · When heated · Try it
- Hafnium + ChlorineHafnium chloride Hf + 2Cl₂ → HfCl₄ · When heated · Try it
- Hafnium + BromineHafnium bromide Hf + 2Br₂ → HfBr₄ · When heated · Try it
- Hafnium + IodineHafnium iodide Hf + 2I₂ → HfI₄ · When heated · Try it
It also blends into a mixture, like an alloy, with 73 other metals when melted together.
Nothing happens when it's simply mixed with 15 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
