· TlF3

Thallium trifluoride (TlF₃) is an ionic ceramic compound composed of thallium and fluorine, belonging to the halide ceramic family. While primarily a research and laboratory material rather than a commodity engineering ceramic, TlF₃ is of interest in specialized applications requiring high-density fluoride materials, including optical systems, nuclear fuel processing, and fluoride-based chemical synthesis where its chemical and thermal properties become relevant.

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.
