On Very Thin Gold Monocrystal Foil,
Abstract
The conditions under which thin, gold monocrystal foil grows, produced with the methods of Suito and Uyeda were examined with an electron microscope. When the growth is slow and undisturbed and when gold chloride is reduced with salicylic acid then crystals can be obtained up to a size of approximately 15 microns or 60 microns and a thickness of about 100A, when reduced with formaldehyde up to a size of approximately 100 microns and a thickness of about 150A. It was established under which circumstances to so called spiral crystals appear. By adding new nutrient solution to the growing crystals the normal growth may continue or new crystals may grow around the edges of host crystals. (Author)
