Summary: The process of sintering of small ice spheres was examined at various temperatures and in different environments by microscopic observation of thin sections. Inference as to the sintering mechanism of small ice spheres was drawn by employing the conventional method used in powder metallurgy. The results obtained indicate that in air saturated with respect to ice the sintering of an ice sphere having R < 100μ is mainly due to volume diffusion (a few specimens showed surface diffusion). Sintering was also observed in a kerosine environment, where the vapor phase was completely excluded; there the growth rate of an ice bond was much lower than in air. Further evidence of material flow due to solid diffusion was obtained from the photomicrographs of thin sections of ice bonds. The phenomena known as regelation, adhesion of ice, and ice bonding of snow may then, all be explained reasonably in terms of sintering.
