Ho3B7W

Ho3B7W is a rare-earth transition metal compound combining holmium, boron, and tungsten, representing an intermetallic or boride-based material system. This composition falls within the family of refractory metal borides and rare-earth compounds, which are primarily of research and development interest rather than established commercial use. Materials in this class are investigated for applications requiring extreme hardness, high-temperature stability, and specialized electronic or magnetic properties, though Ho3B7W itself remains largely in the exploratory phase with limited industrial adoption.
