· JVASP-36112· KNdS2

KNdS₂ is an ternary ceramic compound combining potassium, neodymium, and sulfur—a rare-earth sulfide ceramic belonging to the family of lanthanide chalcogenides. This is a research-phase material studied primarily for its optical and electronic properties rather than established industrial production. The neodymium-sulfur system is of interest in photonics, solid-state lighting, and potentially in high-temperature or specialty optical applications where rare-earth dopants provide unique luminescent or electronic behavior; however, KNdS₂ remains largely in academic investigation and is not yet a standard engineering material in commercial supply chains.

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.
