=================================================================================

Unit cell volume of crystals depending on temperature can be given by,

          V(T ) = VTr exp[α(T − Tr)] ----------------------------- [1718a]

where,
          T -- The temperature,
          V(T ) -- The unit cell volume at the temperature T,
          VTr -- The unit cell volume at the reference temperature Tr,
          α -- The thermal expansion coefficient.

In many cases, one can assume that α has a linear relationship with temperature, given by,

          α = a0 + a1T ----------------------------- [1718b]

where,
          a0 and a1 – The constants for a specific crystal.
