Preface

Preface and structural description of the Encyclopedia of Tungsten Hexachloride 

Tungsten hexachloride (WCl6) is a highly volatile and chemically active transition metal chloride with a molecular weight of 412.52 g/mol, a melting point of about 275°C, and a boiling point of about 346°C. It has a wide range of applications in materials science, chemical industry, and semiconductor technology. With its high purity (>99.9%) and excellent chemical properties, WCl6 is used as a key precursor in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes to prepare high-performance tungsten-based films (~5–10 nm), which are widely used in integrated circuits, hard coatings, and nanomaterials. In addition, WCl6 shows significant advantages as a chlorinating agent in catalyst catalysis, olefin catalytic reactions (yield ~90%), and fine chemicals . However, its high reactivity (e.g., reacting with water to form HCl and WOCl4) poses challenges to production, storage, and safety management, requiring systematic technical support and environmental compliance measures.

With the growing global demand for high-performance materials, the market demand for WCl6 has steadily increased, with global annual production of about 1,000 tons in 2023, and it is widely used in semiconductors (~50%), energy materials (~20%), and catalysis (~15%). At the same time, the environmental impact of WCl6 production (carbon footprint ~50 kg CO2e/kg) and resource efficiency (W recovery rate ~90%) have become research hotspots, and the needs of green manufacturing and sustainable development have promoted the development of new synthesis methods (such as plasma-assisted synthesis) and recycling technologies. In addition, intelligent technologies (such as AI-optimized CVD processes) and global standardization (ISO 17025) provide new opportunities for the industrial upgrading of WCl6.

*Encyclopedia of Tungsten Hexachloride* aims to provide a comprehensive and authoritative technical reference for academia, industry and policy makers, systematically sorting out the physical and chemical properties, synthesis and production technology, application fields, safety regulations, environmental impact and future development trends of WCl6. With scientific rigor and practicality as the core, this encyclopedia covers all aspects from basic theory to industrial practice, and strives to provide solid support for the research and development, application and policy making of WCl6. 

Goal and significance

  • Technology integration : Bringing together the latest research results of WCl6 (such as ALD film thickness control error <0.5 nm) and industrial practice experience (such as production cost ~200 USD/kg) to promote technological innovation.
  • Application guidance : Provide WCl6 application solutions for semiconductor, energy, catalysis and other fields (such as WCl6 increasing the capacity of batteries by ~250 mAh /g).
  • Environmental protection and compliance : Analyze the environmental impact of WCl6 (HCl emissions <10 ppm) and regulatory requirements (such as REACH registration) to promote green manufacturing and sustainable development.
  • Global Vision : Explore the international cooperation and market prospects of WCl6 (demand is expected to reach 2,000 tons in 2030) and promote technology sharing and standardization.
