Carbon Monoxide
Carbon Monoxide
Formula: CO
CAS No: 630-08-0
Carbon Monoxide (CO) is a colorless, odorless, tasteless, and toxic gas composed of carbon and oxygen. It occurs naturally from the combustion of carbon-based materials, with major releases from events such as forest fires and volcanic activity.
Primary Applications:
-
Component of industrial fuel gas mixtures for high-temperature heating in steel, glass, and ceramics manufacturing.
-
Reducing agent in metallurgical processes such as the conversion of iron oxides to metallic iron in steelmaking.
-
Chemical feedstock in the synthesis of phosgene, acetic acid, metal carbonyls, and other specialty chemicals.
-
Atmosphere control in metals processing and electronics manufacturing to maintain specific chemical environments.
-
Use in high-purity gas mixtures, metal oxide reduction, and synthesis of metal carbonyl precursors for specialty deposition in semiconductor processing.
EFC Gases & Advanced Materials supplies high-purity carbon monoxide for demanding chemical, electronics, semiconductor, and metallurgical applications. Our stringent quality control and advanced analytical capabilities ensure consistent purity, safety, and supply reliability.
