Abstract
CAUSAL connexions between dislocations and catalysis have been suggested by a number of workers over the past twenty years1–6. Conclusive evidence, however, has often been lacking because of surface contamination or other effects which could not be implicated as factors in catalysis. Recently an unusual amount of valuable results have been obtained on dislocations and mechanical properties of lithium fluoride crystals. Gilman7–16, Forty17 and Benson et al.18 have determined the role of cleavage in nucleating dislocations in lithium fluoride and described the character of dislocations and stresses needed to produce them. This wealth of experimental results offers a fertile ground for exploring the role of dislocations in catalysis on this simple and well-documented crystalline substance. By using Gilman's8,10,11,15 techniques for cleaving, etching, and stressing crystals it is possible to control the introduction of dislocations to a satisfactory degree and to identify them without spending a major effort on what could be a most illusory problem.
