Dalian Guangming Special Gases Co., Ltd. is located in Zhongge Village, Gezhenbao Subdistrict, Ganjingzi District, Dalian City, Liaoning Province. Established in 2003 with registered capital of RMB 50 million, the company is a high-tech enterprise specializing in the research, development, production, and customized supply of electronic specialty gases, ultra-high-purity industrial gases, and standard gases. It operates within the “New Materials—Advanced Electronic Materials” subsector of China’s national strategic emerging industries and is currently in a phase characterized by both stable large-scale operations and continuous technological iteration.
The company’s core business encompasses over 30 types of electronic specialty gases—including ultra-high-purity nitrogen (99.9999%), electronic-grade ammonia (NH₃), nitrogen trifluoride (NF₃), tungsten hexafluoride (WF₆), and silane (SiH₄)—as well as multi-component standard gases used for environmental monitoring, medical diagnostics, and industrial calibration. Its primary customers are engaged in high-end manufacturing sectors such as semiconductor fabrication, LED packaging, photovoltaic cell etching and deposition, and optical fiber preform production.
The company possesses independently controlled trace-impurity management capabilities. Through its proprietary low-temperature fractional distillation–adsorption coupled purification process and an online ppb-level impurity analysis system (equipped with Agilent 8890 GC-MS and Picarro G2131-i CRDS), it achieves key impurity levels (e.g., HF, H₂O, CO) in NF₃ of ≤50 ppb, fully compliant with the international SEMI F57-1117 standard. The company holds 12 valid invention patents and 28 utility model patents, all with clearly defined ownership.
It has obtained certification under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018; holds the “Production License for Nationally Regulated Industrial Products” (XK13-014-00128), the “Safety Production License for Hazardous Chemicals” (Liao An Xu Zheng Zi [2023] No. 02-0089), and the “Production License for Special Equipment” (TS2221029-2026); serves as a communications member of SAC/TC203; and has participated in the revision of the national standard GB/T 37247-2018.
Notable performance highlights include: bulk supply of NF₃ to SMIC’s Beijing facility (cumulative value exceeding RMB 120 million from 2022 to 2024); integrated silane gas system services for Yangtze Memory Technologies’ Wuhan base (delivered and successfully validated on-site at the fab in 2023); and construction of a dedicated gas supply system for the “Wide-Bandgap Semiconductor Doping Gas Platform” at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences (completed and accepted in 2024).
The company has attained AEO Advanced Certification and, in 2024, completed import registration with Korea’s Ministry of Food and Drug Safety (KFDA) (K-GAS-2024-0882). It supplies electronic-grade ammonia stably to SK Hynix’s Wuxi facility and exports electronic specialty gases to Vietnam and Malaysia. In 2024, its export revenue totaled USD 4.68 million, representing 18.3% of annual revenue. Its primary cooperation models are direct export and local authorized agency arrangements.
