versus -3 to -4℃ for dry ice).
英文: Release of silver iodide
(AgI) into an existing supercooled cloud (i.e., air temperature between -39 and -5 celsius) can convert water vapor to ice crystals, which is called sublimation.
英文: Silver iodide nano-powder has been produced by salt of silver and iodide in an alcohol solvent. The optimal conditions of the process has been studied by Latin square experiments.
