ABSTRACT:
A process for preparing fine-grained slush of low-boiling gases is characterized in that the liquefied gas or the very cold gas under high pressure is relieved from stress in a nozzle alternately first to a pressure below the pressure of the triple point in the gas-ice range and subsequently to a pressure above the pressure of the triple point in gas-liquid range.
