SEM images of the starting material synthesized and used in this work. (a) Agglomerate of α-hemihydrate crystals. (b) Single hemihydrate crystal, showing the typical crystal habit and pencil-shape tip of α-hemihydrate. Some crystallographic planes are recognizable: {111} facets in yellow, {100} facets in red, {011} facets in green. |
