Iron tetraboride (FeB4) is a superhard superconductor (Tc < 3K) consisting of iron and boron. Iron tetraboride does not occur in nature and can be created synthetically.[1][2] Its molecular structure was predicted using computer models.[3]

It has been shown that under pressure, iron tetraboride transforms into a transparent phase with lower conductivity, converting from a superconductor to a semiconductor.[4] Another study that pressurised the compound up to 1 TPa identified that it further becomes a conductor after its semiconducting phase.[5]
