 note = {Anisotropic thermal expansion of potassium nitrate crystal has been studied from - 177°C up
to 325°C by the X-ray diffraction method. The values of lattice constants, thermal expansion
coefficients and densities have been given at sixteen temperatures.
The anisotropic temperature factors for phase II have been determined at - 177°, 30° and
122.5°C.
It was recognized that y component of the atomic co-ordinate of NO_3^- ions, which are oriented
perpendicular to b axis, has rather large temperature dependence.
Anisotropic expansion and thermal motions of atoms in potassium nitrate are discussed qualitatively
in relation to the crystal structure.},
