· JVASP-42081· Ac2NiIr

Ac2NiIr is an intermetallic compound combining actinium, nickel, and iridium in a stoichiometric ratio. This is a research-phase material studied primarily for its potential in high-temperature and nuclear applications, where the combination of actinium's nuclear properties with the refractory characteristics of nickel and iridium offers theoretical advantages. The material remains largely experimental; its development is driven by interest in advanced metallic systems for extreme environments rather than established industrial production.
