Record #117335:

The slow growth of ice crystals in water / Samuel C. Colbeck.

Title: The slow growth of ice crystals in water / Samuel C. Colbeck.
Author(s): Colbeck, Samuel C.
Date: 1992.
In: CRREL Report. (1992.), Vol. 92-3 (1992)
Abstract: Grown in supercooled water at rates spanning those for slush (1x10⁻⁶ g h⁻¹) to those for frazil (3x10³ g h⁻¹). All were disks with aspect ratios between 2 and 35, which increased with growth rate. Growth rates were less than expected from theory, possibly because of crowding. Shapes showed transition from well-rounded to highly faceted as growth rate increased. Even at lower growth rates, crystals do not undergo metamorphism during growth, so kinetics of crystal growth control shape over entire range of growth rates investigated. This explains why crystals were disk-shaped, unlike well-rounded ones seen in slush.
