The ice‐nucleation activity of AgI particles is investigated. The critical supercoolings are determined for water drops with particles situated on the drop surface and suspended into the drop volume. The ice‐nucleation activity of the AgI particles decreases with the gradually penetration of the particles into the volume. A large alteration (about 10 °C) for the mean freezing temperature is established. An attempt is made to explain this phenomenon with the lowering of the nucleation work on the three‐phase particle/water/water vapour contact.
