· JVASP-5323· TmCl2

Thulium dichloride (TmCl₂) is an inorganic ionic ceramic compound containing thulium, a rare-earth element, in the +2 oxidation state. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, with applications emerging in rare-earth chemistry, optical systems, and advanced ceramics development. TmCl₂ is notable within the rare-earth halide family for its potential in solid-state lasers, luminescent devices, and as a precursor for synthesizing high-purity thulium oxides and other functional ceramics used in photonics and materials research.

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.
