Thermal etching of sodium chloride II. Edge effects on surface structure
Thermal etching of (100) surfaces of NaCI single crystals has been studied by using different heating conditions and gaseous environments. It is shown that the high temperature surface topography is strongly dependent on the conditions of heating (position and symmetry of heating elements, etc.) and...

| Sumario: | Thermal etching of (100) surfaces of NaCI single crystals has been studied by using different heating conditions and gaseous environments. It is shown that the high temperature surface topography is strongly dependent on the conditions of heating (position and symmetry of heating elements, etc.) and on the temperature distribution in the sample. The different patterns observed in each case are discussed in terms of the theory of crystal growth elaborated by Cabrera and Vermilyea and the model of dissolution of a crystal with protected edges proposed by Frank. © 1964. |
