The effect of pressure on the size of a crystal depends on the type of crystal. At high pressures, some crystals can undergo a process called pressure-induced amorphization, which can reduce the size of the crystal by rearranging the atoms to form a disordered structure. Other crystals may experience an increase in the lattice parameter, resulting in a larger size crystal.An example of the effect of pressure on the size of a crystal is when zinc oxide is pressurized to 17.5 GPa. At this pressure, zinc oxide undergoes pressure-induced amorphization and its crystal size decreases dramatically.
