Liquid Carbon Dioxide (CO2) is the source of all dry ice products. The liquid is stored at 20 bar and around -20°C. It is released through a nozzle to 1 bar at which point dry ice ‘snow’ is created. This snow is compressed and extruded at around 1500 psi to form pellets, slices and blocks of dry ice.

Instead CO2 performs "deposition", going directly from gas to solid (similar to frost crystals forming from water in the air). The solid CO2 (dry ice) goes directly to a gas when the dry ice is placed in room temperature surroundings. This process is called "sublimation".
