The geometry of the unit cell is defined as a parallelepiped providing six lattice parameters taken as the lengths of the cell edges a b c and the angles between them α β γ.

The packing density also known as the atomic packing factor APF is essentially the fraction of the volume of atoms that occupy a crystal structure. Concept of atomic orbitals as one-electron wave functions. In fact the atoms in solid materials are in constant motion rapidly changing positions.

Titanium is a lustrous transition metal with a silver color low density and high strengthTitanium is resistant to corrosion in sea water aqua regia and chlorine. This unit cell is the simplest for people to understand although it rarely occurs in nature due to its low packing. Other well-known SICs such as lithium garnet and NASICON do not exhibit bcc anion packing but still achieve high Li ionic conductivity of 1 mS cm 1 at RT.
