ceramic

· P2Ir

P2Ir is an intermetallic ceramic compound combining phosphorus and iridium, representing a rare refractory ceramic in the transition metal phosphide family. This material is primarily of research and advanced materials interest, valued for applications requiring extreme hardness, chemical inertness, and thermal stability in harsh environments where traditional ceramics or metals prove inadequate.

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.
