TEXT: At pressures close to 1.8-101 k9/cm , NaCl acquires a structure
qf the Cs'Cl type. Its original lattice is stable, the constant equals
39-0.06 3 at atmospherioc pressure. The density of the new phase is
2:535 glem. and the discontinuity in the specific volume during the
transformation is 14-Z/~- Allowing for the faot that the distance between
the oppositely charged ions increases by Y14 the lattice constant of
the new phase is found to be 3.35 L 71hen the pressure is released* the
new phase is usually maintained. Shear deformation might play a
significant role in the phase transition. There are 1 figure and 1 table.
