“C R Y S T A L S”

In “C R Y S T A L S,” filmmaker Thomas Blanchard captures the slow, inexorable growth of potassium phosphate crystals. He took over 150,000 images — one per minute — to document the way crystals formed as the originally transparent liquid evaporated. Some crystals branch into fractals. Others bulge outward like a condensing cloud or a sprouting mushroom. (Video and image credit: T. Blanchard)

Czochralski technique - The method is named after Polish scientist Jan Czochralski. Silicon Wafer production. Approximately 80–90% of silicon wafers used in the semiconductor industry are manufactured using the Czochralski method.

Ice Without Gravity

Astronaut Don Pettit is back in space, and that means lots of awesome microgravity experiments. Here, he grew thin wafers of ice in microgravity in a -95 degree Celsius freezer. Then he took the ice wafers and photographed them between crossed polarizers, creating this colorful image. The colors highlight different crystal orientations within the ice and give us a hint about how the freezing front formed and expanded. I can’t wait to see more examples! (Image credit: D.

Under a macro lens, even a petri dish worth of fluids comes vividly to life. Here, artist Scott Portingale explores crystallization, Marangoni effects, and other phenomena alongside a haunting soundtrack from musician Gorkem Sen. Enjoy! (Image and video credit: S. Portingale et al.)

Anyone know what conditions determine the max diameter of a crystal boule synthetically produced using the Czochralski method? And/or good resources to learn the nuances of the method?
