ceramic

· Yb2KF7

Yb2KF7 is a rare-earth fluoride ceramic composed of ytterbium, potassium, and fluorine. This material belongs to the family of rare-earth fluorides, which are primarily investigated for photonic and optical applications where high transparency and low phonon energy are advantageous. Research-stage compounds like this are explored for laser host matrices, upconversion phosphors, and specialized optical coatings where conventional oxides fall short due to phonon-limited performance.

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.
