Ammonia
Formula: NH3, R-717
CAS No: 7664-41-7
Ammonia (NH3) is a colorless, alkaline gas with a distinct, pungent odor. It serves as a critical feedstock in numerous industrial processes, including semiconductor and advanced materials manufacturing, where it is essential in Chemical Vapor Deposition (CVD) for the formation of silicon nitride layers.
Applications include:
-
Deposition of silicon nitride layers in semiconductor manufacturing (CVD).
-
Neutralization of acids in chemical processing and wastewater treatment.
-
Surface treatment in metals, electronics, and specialty manufacturing.
-
Refrigeration in food processing, cold storage, and ice production (R-717).
-
Production of nitrogen-based chemicals, fertilizers, and specialty compounds.
EFC Gases & Advanced Materials supplies high-purity ammonia to meet the stringent quality demands of semiconductor, refrigeration, and industrial applications. Our rigorous analytical verification, controlled packaging, and secure logistics ensure consistent quality from production to point-of-use.
