Upstream tungsten raw-material tightening has continued to push high-purity
tungsten hexafluoride (WF6) prices higher. CSSC Special Gas said its 6N-grade
WF6 for semiconductor use, packaged in 47L cylinders, is being quoted at roughly
2,000-2,500 yuan/kg; the company reported capacity and orders are at full
utilization while fulfilling domestic and overseas customer orders.
