· JVASP-75502· Si2MoAs

Si2MoAs is an intermetallic compound combining silicon, molybdenum, and arsenic, representing a specialized metal-ceramic hybrid material from the refractory intermetallic family. This compound exists primarily in research and development contexts, with potential applications where hardness, thermal stability, and chemical resistance are priorities, though its arsenic content creates handling and environmental constraints that limit widespread industrial adoption compared to conventional refractory alloys. Engineers would consider this material for high-temperature applications or wear-resistant coatings in specialized environments where its unique phase stability offers advantages over more common alternatives, provided toxicity and processing challenges can be managed.

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.
