Absence of superconductivity in LK-99 at ambient conditions

Understand

The report of synthesis of modified Lead apatite (LK-99) with evidence of superconductivity at more than boiling water temperature has steered the whole scientific community.

• There have been several failures to reproduce superconductivity in LK-99 including partial successes.
• Here, we have continued our efforts to synthesize phase pure LK-99 with improved precursors.
• The process has been followed as suggested by Sukbae Lee et.
