Determine crystal structure from density
WebPerhaps the most common crystal structure is Face-Centered Cubic (FCC). The crystal structure is based on the Bravais lattice of the same name, with a single atom at each lattice point on the cube’s corners and faces. FCC is one of the most stable crystal structures and has the highest packing density. http://web.boun.edu.tr/jeremy.mason/teaching/ME212/chapter_03_04_sol.pdf
