What You Need to Know
Slurry ice is a phase changing refrigerant made up of millions of ice "micro-crystals" formed and suspended within a solution of water and a freezing point depressant. Some compounds used in the field are salt, ethylene glycol, propylene glycol, alcohols like isobutyl and ethanol, and sugars like sucrose and glucose. Slurry ice has greater heat absorption compared to single phase refrigerants like brine, because the melting enthalpy of the ice is also used.
