· CeSiIr

CeSiIr is a ternary intermetallic ceramic compound combining cerium, silicon, and iridium. This is a research-phase material within the family of rare-earth transition metal silicides, engineered for extreme high-temperature applications where conventional superalloys reach their performance limits. The iridium addition provides superior oxidation resistance and refractory characteristics compared to binary cerium silicides, making it a candidate for aerospace and power generation systems operating in oxygen-containing environments at temperatures where traditional materials degrade.

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.
