Studies of silver iodide ice-forming activity—II. influence of aerosol particle size and structure on the ice-forming activity

The fraction of silver iodide aerosol particles active at −5 and −10°C has been found not to be a monotonic function of the radius of aerosol particles. To explain this phenomenon, silver iodide aerosols were supposed to be mixtures of particles of two structural modifications. Electron diffraction...

Description
Summary:The fraction of silver iodide aerosol particles active at −5 and −10°C has been found not to be a monotonic function of the radius of aerosol particles. To explain this phenomenon, silver iodide aerosols were supposed to be mixtures of particles of two structural modifications. Electron diffraction studies showed silver iodide particles with radii less than 150–200 Å to have the hexagonal modification, whereas larger particles to have the cubic low-temperature modification. The anomaly in the dispersity dependence of the ice-forming activity gave the same phase transition radius.
