In this paper, the SrSO 4 dendrites were prepared by diffusion method. Electron backscattered diffraction (EBSD) technique is used to determine the crystallographic orientations of SrSO 4 dendrites. It is shown that the SrSO 4 dendrites grow in (001) plane, and all short main branches grow along <100>, but the long main branches grow along <110>, <130> or <140> directions. The growth morphology of SrSO 4 dendrites is controlled by not only their internal structure but also external growth conditions. The internal structure of SrSO 4 dendrites influences the character of the growth direction vertically <001>. The change of the ions concentration in the diffusion system leads to the evolution from <110> to <140> of the long main branches. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
