Abstract

A set of measured thermal shifts {Δϑi} of diffraction peaks is numerically processed by introducing special variables z i , y i , and x i , and linear relations are obtained between the thermal shifts characterized by the values of z i as functions of the variables x i and y i , which depend on the crystal-plane indices and the unit-cell parameters of the crystal. After the least-squares fit, these relations can be represented in a graphical form. The thermal expansion coefficients are determined directly from these plots or analytically.
