Abstract

This paper reports the experimental discovery of superconductivity in titanium (Ti) metal at high pressures, reaching a critical temperature (Tc) above 20 K in a wide pressure range (180-240 GPa). The maximum Tc (onset) exceeds 26.2 K, a record high among elemental superconductors. The findings challenge conventional BCS theory predictions and suggest unconventional mechanisms, opening new avenues for designing high-Tc superconductors.
