· JVASP-154517· HoSi3

HoSi₃ is a rare-earth silicide ceramic compound combining holmium with silicon, belonging to the family of intermetallic silicides studied for high-temperature structural applications. This material is primarily investigated in research contexts for aerospace and advanced thermal systems where oxidation resistance and refractory properties are critical, though industrial deployment remains limited compared to established silicide ceramics like MoSi₂. The holmium addition offers potential advantages in tailoring thermal expansion and high-temperature strength, making it a candidate for next-generation propulsion components and thermal protection systems.

Regulatory Screening

Environmental

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.
