· WCl4

Tungsten tetrachloride (WCl₄) is a halide compound of tungsten that exists primarily as a research chemical rather than an established engineering material. It belongs to the metal halide family and serves mainly as a precursor or intermediate compound in synthesis routes for tungsten-containing materials, coatings, and catalysts. In industrial practice, WCl₄ is used in chemical vapor deposition (CVD) processes to deposit tungsten films and in the production of tungsten carbides and other refractory compounds; its appeal lies in its ability to deliver tungsten at lower temperatures or with better film quality control than alternative tungsten sources, making it relevant for microelectronics and hard-coating applications.

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.
