ceramic

· KZnF3

KZnF₃ is a fluoroperovskite ceramic compound combining potassium, zinc, and fluorine in a perovskite crystal structure. This material is primarily of research and emerging technology interest rather than established industrial production, with potential applications in optics, photonics, and solid-state chemistry where fluoride-based ceramics offer advantages in transparency, thermal stability, and chemical inertness.

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.
