· Ho4 Si4

Ho₄Si₄ is an intermetallic compound composed of holmium and silicon, belonging to the rare-earth silicide family of semiconducting materials. This compound is primarily of research and development interest rather than established in high-volume production, with potential applications in thermoelectric devices, magnetic materials, and high-temperature electronics where the combination of rare-earth and silicon elements offers unique electronic and thermal properties.

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.
