Abstract Using synchrotron high-pressure X-ray diffraction at cryogenic temperatures, we have established the phase diagram for calcium up to 110 GPa and 5–300 K. We discovered the long-sought for theoretically predicted β-tin structured calcium with I4 1 /amd symmetry at 35 GPa in a s mall low-temperature range below 10 K, thus resolving the enigma of absence of this lowest enthalpy phase.

Most metal crystals are one of the four major types of unit cells. For now, we will focus on the three cubic unit cells: simple cubic (which we have already seen), body-centered cubic unit cell, and face-centered cubic unit cell—all of which are illustrated in .
Here''s what I got. In order to be able to calculate the edge length of the unit cell, you need to start from the characteristics of a face-centered cubic system. As you know, a face-centered cubic system is characterized by a unit cell that has a total of 14 lattice points one lattice point for every one of the eight corners of the unit cell one lattice point for every one of the six faces of
