Evolution of ΔL/L with temperature in 2°AP-β along the principal axes of the thermal expansion tensor, namely along the [010] (blue), [100] (green) and approximately [101] (red) crystallographic directions. Solid lines represent the closest linear fits for the ΔL/L versus ΔT relations. The inset on the right represents the temperature range where the changes are strictly proportional to T.
