· JVASP-112958· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
