Differences Between Amorphous & Crystalline Solids

WebThere are two main classes of solids: crystalline and amorphous.What distinguishes them from one another is the nature of their atomic-scale structure. The essential differences are displayed in Figure 2.The salient features of the atomic arrangements in amorphous solids (also called glasses), as opposed to crystals, are illustrated in the figure for two … WebThe amorphous form of a drug usually exhibits higher solubility, faster dissolution rate, and improved oral bioavailability in comparison to its crystalline forms. However, the amorphous forms are thermodynamically unstable and tend to transform into a more stable crystalline form, thus losing their advantages.
