Dissolution slowness surfaces of cubic crystals

Abstract

The first part of this paper offers a tensorial method that gives analytical equations for the dissolution slowness surface of cubic crystals. Conditions for the proposed equations are outlined. The non-centrosymmetric class 2 3 is treated as an example. The evolution of the shape of the slowness surface with the higher rank of the dissolution tensors is studied, using in particular a three-dimensional graphical representation of the slowness surface. The conditions for obtaining slowness surfaces with a complex shape and an increasing number of extrema are discussed.
