The X-ray diffraction measurements of a CaAl4O7 single crystal have been performed at seven temperatures above ambient, over a 300-773 K temperature range. The evolution of the lattice parameters was used to determine the second rank thermal expansion tensor of the crystal. The thermal expansion is minor and highly anisotropic. The principal thermal expansion coefficients are: 7.91_10-6, 1.12_10-5 and -3.48_10-6 deg-1. The results are discussed in relation to the crystal structure.
