· LiIr

LiIr is a ceramic intermetallic compound composed of lithium and iridium, representing a materials chemistry combination primarily of academic and research interest rather than established industrial production. This compound belongs to the family of metal-ceramic intermetallics that have been studied for their potential combination of light-element (lithium) and refractory metal (iridium) properties. While LiIr itself has not achieved widespread commercial adoption, compounds in this chemical family are investigated for extreme-environment applications where thermal stability, corrosion resistance, and unique bonding characteristics between light and heavy elements could offer advantages over conventional ceramics or superalloys.
