The cracking behavior of gibbsite crystallites is analyzed by Zhi‐Gang Chen, Zhonghua Zhu, and co‐workers in article number 1800201 . The cover picture represents the internal morphology of gibbsite crystallites after calcination at 260°C. Phase transformation and crystallites shrinkages introduce clearly visible crack during calcination. Detailed investigation shows that the cracks propagate from pores formed inside the crystallite bulk.
