· JVASP-40602· ScTaRu2

ScTaRu2 is a complex ceramic compound combining scandium, tantalum, and ruthenium—a high-entropy or multi-principal-element ceramic representative of emerging research materials designed for extreme environments. This material belongs to the family of refractory ceramics and represents experimental development rather than established industrial production; such compounds are investigated for applications requiring simultaneous resistance to high temperature, oxidation, and mechanical degradation where conventional ceramics fall short.

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.
