Crystalline to amorphous
WebJul 4, 2024 · Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range … WebApr 12, 2024 · Depending on how the amorphous ice is made, it might contain a crystalline fraction to start with, nm-sized crystalline seeds, adsorbates or trapped impurities—all of which greatly affect J and G. In addition, the microporosity and density of the amorphous ice vary very much with formation conditions.
