What does niobium react with?
Niobium makes a new substance with 9 other elements and chemicals in our lab:
- Niobium + BoronNiobium boride Nb + 2B → NbB₂ · Only in a very hot furnace · Try it
- Niobium + CarbonNiobium carbide Nb + C → NbC · Only in a very hot furnace · Try it
- Niobium + NitrogenNiobium nitride 2Nb + N₂ → 2NbN · Only when heated very strongly · Try it
- Niobium + OxygenNiobium oxide 4Nb + 5O₂ → 2Nb₂O₅ · When heated · Try it
- Niobium + FluorineNiobium fluoride 2Nb + 5F₂ → 2NbF₅ · At room temperature · Try it
- Niobium + SulfurNiobium sulfide Nb + 2S → NbS₂ · When heated · Try it
- Niobium + ChlorineNiobium chloride 2Nb + 5Cl₂ → 2NbCl₅ · When heated · Try it
- Niobium + BromineNiobium bromide 2Nb + 5Br₂ → 2NbBr₅ · When heated · Try it
- Niobium + IodineNiobium iodide 2Nb + 5I₂ → 2NbI₅ · 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 16 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
