· Ho4 Si4 Ir4

Ho₄Si₄Ir₄ is an intermetallic semiconductor compound combining holmium, silicon, and iridium in a 1:1:1 stoichiometric ratio. This is an experimental/research material explored primarily for its electronic and thermal properties at elevated temperatures, with potential applications in thermoelectric devices and high-temperature electronics where rare-earth intermetallics offer unique band structure characteristics. The incorporation of iridium—a refractory transition metal—and holmium—a lanthanide element—suggests investigation into materials for extreme environments where conventional semiconductors degrade.

Export Control

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.
