Dry ice and its uses

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 (a sublimation process). Dry Ice is manufactured by compressing and cooling gaseous CO2 under high pressure to produce liquid CO2 initially. Dry ice is a molecular crystal in which the crystal lattice consists of carbon dioxide molecules rather than individual carbon or oxygen atoms.

  • Due to its extremely low temperature of -78°c, dry ice is often used as an alternative to refrigeration for foodstuffs and medical supplies.
  • Special dry ice pellets are used for industrial cleaning.
