· JVASP-79235· YMg3

YMg3 is a rare-earth magnesium intermetallic ceramic compound combining yttrium and magnesium in a 1:3 stoichiometric ratio. This material belongs to the family of rare-earth magnesium compounds, which are primarily explored in research and advanced applications for their potential to combine the lightweight properties of magnesium with the thermal stability and hardness contributions of yttrium oxide phases. YMg3 is not a widespread commercial material but represents the type of intermetallic system investigated for high-temperature structural applications, protective coatings, and composite reinforcement where magnesium-based ceramics offer weight savings over traditional refractory oxides.
