Abstract
Freeze fracture scanning electron microscopy (FFSEM) is shown to be a reliable technique for the study of chemically generated voids in concentrated emulsions. The gassing of such emulsions involves the reaction of ammonium nitrate and sodium nitrite to produce dinitrogen, the reaction being strongly dependent on pH and temperature. The changes in the size and distribution of voids were monitored from their inception by arresting the gassing reaction at various stages. The gassing temperature and the emulsion viscosity are both shown to bring about dramatic differences in the size and distribution of gas bubbles entrapped in an emulsion matrix.
