THE DISSOLUTION OF ICELAND SPAR CRYSTALS - THE EFFECT OF SURFACE-MORPHOLOGY

Journal article

The effect of surface morphology on the dissolution rate of Iceland Spar crystals has been examined by a rotating disk method. A cleaved (100) surface was found to be initially unreactive even in 10-3M HCl. Subsequently dissolution develops and surface roughness increases until a steady state is reached. An equation describing the transition is presented. Dissolution experiments in the pH range 6.0-7.0 with deliberately roughened surfaces and with surfaces misoriented at a known angle to the (100) plane are described and the dissolution rates correlated with the surface morphology as revealed by electron microscopy. © 1986.
