Nitrogen Trifluoride (NF₃): Major Capacity Expansion Signals Demand Growth
Investment AnNOuncement: Hubei Heyuan Gas Co., Ltd. announced a significant expansion in electronic specialty gases on March 3, 2026, planning to invest ¥684 million to expand its Yichang Electronic Specialty Gases and Functional Materials Industrial Park with a 4,500 tons/year electronic grade nitrogen trifluoride (NF₃) project .
Project Structure: The expansion will be constructed in two phases over three years:
-
Phase I: 3,000 tons/year NF₃ production facility, storage, filling systems, and supporting infrastructure
-
Phase II: 1,500 tons/year NF₃ (combined with existing 500 t/a facility to reach 2,000 t/a total capacity)
Product Application: Electronic grade nitrogen trifluoride is an excellent plasma etching gas widely used in microelectronics manufacturing, offering favorable etching rates and selectivity. It is essential for:
-
Semiconductor production
-
Flat panel display manufacturing
-
Photovoltaic cell fabrication
Financial Projections: According to the feasibility study, the project has an estimated investment profit rate of 24.50% with a payback period of 5.27 years (after tax, including construction period) .
Strategic Context: This expansion builds upon existing industrial park infrastructure spanning 880 mu (approximately 58.7 hectares), which produces various electronic specialty gases including:
-
Tungsten hexafluoride (WF₆)
-
Silane and disilane
-
Silicone-based functional new materials
Safety Features: The project features advanced automation with Distributed Control System (DCS) integrated with combustible and toxic gas detectors throughout the facility, enabling real-time monitoring with automatic adjustment capabilities when operating conditions become abnormal .
