· JVASP-40050· HoMg3

HoMg3 is an intermetallic ceramic compound containing holmium and magnesium, representing a rare-earth magnesium system with potential for high-temperature and structural applications. This material family is primarily explored in research contexts for aerospace, catalytic, and advanced structural applications where the combination of rare-earth and lightweight magnesium properties may offer advantages in elevated-temperature stability or specialized chemical functionality. The intermetallic nature typically provides superior hardness and thermal stability compared to unreinforced magnesium alloys, though practical engineering use remains limited pending further characterization and scalability development.
