Crystal and amorphous structure
WebApr 12, 2024 · Amorphous solids, also known as non-crystalline solids, are a class of materials that lack a long-range ordered structure. Unlike crystalline solids, amorphous … Webamorphous structures. • We can predict the density of a material, provided we know the atomic weight, atomic radius, and crystal geometry (e.g., FCC, BCC, HCP). • Material properties generally vary with single crystal orientation (i.e., they are anisotropic), but properties are generally non-directional
