Abstract
Etch pits with edges parallel to directions on (001) surface of sodium chloride have been observed by using ethyl alcohol as an etchant. It has been found that ethyl alcohol can distinguish between annealed and fresh dislocations. It is shown that by varying the concentration of mercuric chloride in ethyl alcohol, etch pits with edges parallel to and directions can be obtained. The reason for the rotation of etch pits is explained on the basis of the change in the lateral displacement velocity of surface steps along different directions.Keywords
