High-purity nitrogen trifluoride (NF₃) gas supplied from China for semiconductor manufacturing, electronics, and specialty applications.
High-purity nitrogen trifluoride (NF₃) for semiconductor chamber cleaning, plasma etching, and flat-panel display manufacturing.
Nitrogen trifluoride is a colorless and odorless gas in its pure form. When mixed with impurity gases, it may appear yellowish with a musty or irritating odor. NF₃ is non-flammable but can support combustion, acting as a strong oxidizing agent at elevated temperatures. It slowly decomposes above 350°C, releasing highly reactive fluorine species. NF₃ serves as a specialized cleaning gas for semiconductor manufacturing equipment (particularly for chemical vapor deposition chamber cleaning), as an etchant in plasma processing, and in the production of flat-panel displays and photovoltaic cells. It is typically transported as a liquefied compressed gas.
