Abstract
There are many publications describing the resistance to cracks caused by thermal shock in ceramic bodies by using quality figures. In Light Metals 1988 these figures were applied to anodes for the aluminium industry. Such quality figures allow a simple and fast appraisal of an anode’s tendency to thermal shock. The application of these quality figures in practice has shown, however, that a modification of the definition of the quality figure thermal shock is advisable. The mechanical stresses, which occur when a heat wave penetrates the cold anodes after they are set in the hot electrolyte, were calculated three-dimensionally. The results confirm the validity of the already mentioned quality figures on the one hand and correspond very well to the shape of cracks in anodes observed in practice. The influence of the conditions under which the anodes are set and of the properties of the anodes on the mechanical stresses which arise, is reported on.
