· NaCN

Sodium cyanide (NaCN) is an ionic ceramic compound classified as a cyanide salt, consisting of sodium cations paired with cyanide anions. While historically used in metallurgical processing (gold and silver extraction, case hardening of steel), modern engineering applications are extremely limited due to its extreme toxicity and environmental hazards; it is primarily encountered in legacy industrial processes or specialized chemical synthesis rather than as a structural or functional engineering material. Engineers would avoid specifying NaCN for new designs in favor of safer alternatives, and its presence in materials databases reflects historical industrial relevance rather than contemporary material selection.

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.
