dry ice


Dry Ice is the common name for solid carbon dioxide (CO2). It gets this name because it does not melt into a liquid when heated; instead, it changes directly into a gas.


  • dry ice is carbon dioxide in solid-state
  • the chemical formula is CO2
  • a translucent, white solid; at normal temperatures sublimes directly into a gas without passing through a liquid phase
  • non-flammable
  • the temperature is -78ºC
  • asphyxiant
  • colourless gas with a slightly pungent odour which is only detectable in high concentration


Dry ice can be a very serious hazard in a small space that isn’t well-ventilated. As it melts, it turns into carbon dioxide gas. In a small space, this gas can build up. If enough carbon dioxide gas is present, a person can become unconscious, and in some cases, die.

10kg of dry ice sublimes into about 5.4 m3 of carbon dioxide gas.


Dry ice is an attractive resource for virtually all industrial sectors. It is ideal for any process that requires effective refrigeration due to its cooling effect, excellent for transport of chilled or frozen food due to its anti-bacterial properties and essential for the transportation of medicines for vaccines in the pharma industry.
