· JVASP-15330· DySi2Ru2

DySi₂Ru₂ is an intermetallic ceramic compound combining dysprosium, silicon, and ruthenium, belonging to the family of rare-earth silicides with transition metal additions. This material is primarily of research interest for high-temperature structural applications, where the combination of rare-earth and refractory elements is explored to achieve enhanced strength and oxidation resistance at elevated temperatures. The ruthenium addition distinguishes it from conventional rare-earth silicides, potentially improving ductility and damage tolerance compared to brittle ceramic alternatives, though industrial-scale deployment remains limited and the material is best considered an advanced experimental compound under investigation for aerospace and energy 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.
