“…In nature, the most common are crystalline solids, the structure of which is characterized by a geometrically rigorous ordering of particles (atoms, ions) in three-dimensional space. The crystalline state is stable under normal conditions and is characterized by the lowest internal energy [13]. Solid crystalline substances have clear geometric forms, certain melting points, in most cases they exhibit anisotropy, or their physical properties (refractive index, thermal conductivity, rates of dissolution and crystal growth, etc.)…”
