    • Abstract


      Some elevated microdisks are reported on (100) cleavages and (110) fractured faces of NaCl, produced by the etchant reported by Davidge and Whitworth (1961). It is observed that the structure of the disks is similar on both the faces, but does not coincide with the matched faces. It is shown that these disks are not formed due to the protective action of microbubbles during the etching process but formed at the sites of localized impurities.
