Lah10
Lanthanum decahydride is a polyhydride or superhydride compound of lanthanum and hydrogen (LaH10) that has shown evidence of being a high-temperature superconductor. It has a superconducting transition temperature TC ~ 250 K (−23 °C; −10 °F) at a pressure of 150 gigapascals (GPa), and its synthesis required pressures above ~160 GPa.
