We report a dendritic crystallization of ionic melt of lead molybdate
(PbMoO4) under a concentric thermal field. The solidified melt is a Pb
MoO4 single crystal with [001] axis normal to surface, The dendrite ar
ms propagate and branch along [310] and [130], forming a well-organize
d surface structure. It is evident that the interaction between a cati
on to its second-nearest anions determines the dendrite development an
d melt solidification.
