A colourless, odourless and non-flammable gas with the formula CO2.
Carbon dioxide is formed during respiration in animals, photosynthesis in plants and whenever carbon-containing material decomposes or is burnt. It reacts with carbonat temperatures above about 500oC and produces carbon monoxide. Accordingly, it is an important, if small, constituent of most heat treatment carrier gases and carburising atmospheres.
Carbon dioxide will not support combustion and is frequently used in fire extinguishers for use on electrical equipment. It should never be used in a confined space since it can cause asphyxiation. It is slightly soluble in water and is the cause of the fizz in lemonade and sparkling water.
Properties: | Melting point | -56.6°C |
Boiling point | -78.5°C | |
Relative density | 1.53 (Air = 1) | |
Flash point | Non-flammable |
Widely used in its solid form as a refrigerant.
See also dry ice.
