· JVASP-119460· KLaF4

KLaF₄ is a rare-earth fluoride ceramic compound combining potassium, lanthanum, and fluorine—a member of the laser crystal family that has attracted research interest for optical and photonic applications. This material is investigated primarily in academic and specialized optics contexts for its potential as a solid-state laser medium or optical component, where its fluoride composition offers wide transparency windows and thermal properties distinct from oxide ceramics. Its selection would be driven by needs for UV-to-infrared transmission, low phonon energy, or specific luminescence characteristics rather than conventional structural 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.
