· Sc1 Ta1 Os2

Sc₁Ta₁Os₂ is an experimental ternary intermetallic compound combining scandium, tantalum, and osmium—a research-phase material rather than an established engineering standard. This composition belongs to the family of high-entropy and refractory metal systems, investigated primarily for extreme-environment applications where conventional superalloys reach their limits. The material's potential lies in ultra-high-temperature stability and hardness driven by osmium's density and refractory character, though industrial adoption remains limited pending validation of reproducibility, processability, and cost-benefit over established alternatives like nickel superalloys or tungsten-based composites.

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.
