· Si2 Ni2 Pr1

Si₂Ni₂Pr is an intermetallic compound combining silicon and nickel with praseodymium, belonging to the rare-earth semiconductor family. This is a research-phase material being investigated for high-temperature structural applications and functional device components where the combination of intermetallic strength and rare-earth properties may offer advantages over conventional binary Ni-Si systems. Interest in this compound stems from potential use in next-generation thermoelectric devices, high-temperature electronics, and advanced composites where rare-earth doping can modify electronic and mechanical behavior.
