Growth and EBSD determination of Celestite SrSO4 dendrites

In this paper, the SrSO4 dendrites were prepared by diffusion method. Electron backscattered diffraction (EBSD) technique is used to determine the crystallographic orientations of SrSO4 dendrites. It is shown that the SrSO4 dendrites grow in (001) plane, and all short main branches grow along , but the long main branches grow along , or directions. The growth morphology of SrSO4 dendrites is controlled by not only their internal structure but also external growth conditions. The internal structure of SrSO4 dendrites influences the character of the growth direction vertically . The change of the ions concentration in the diffusion system leads to the evolution from to of the long main branches. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
