WCl2

WCl₂ (tungsten dichloride) is a halide compound of tungsten that exists primarily as a research material rather than a commercial engineering commodity. It belongs to the family of tungsten halides and is of interest in materials synthesis, chemical vapor deposition (CVD) precursors, and specialized metallurgical applications where tungsten-containing intermediates are needed. The compound is notable for its potential role in producing high-purity tungsten coatings and as a starting material for tungsten-based catalysts and advanced ceramics, though it remains largely confined to laboratory and pilot-scale use rather than high-volume industrial production.
