本文报道了以SrCO_3和V_2O_5为助熔剂，在密闭坩埚和敞开坩埚中用助熔剂法生长的Ni_3V_2O_8单晶的形貌。在较高的垂直温度梯度下，发现在密闭坩埚中生长的晶体为柱状，而在敞开坩埚中生长的晶体为板状。根据Ni_3V_2O_8的理论形貌，提出了坩埚中不同形貌的可能原因。
In this paper, we report the morphologies of Ni3V2O8 single crystals grown by the flux method in closed and opened crucibles using SrCO3 and V2O5 as flux. Under a high vertical temperature gradient, the morphology of the grown crystals in a closed crucible is found to be pillar-like, which is different from the plate-like feature for crystals grown in an opened crucible. On the basis of the theoretical morphology of Ni3V2O8, the possible reasons for different morphologies in the crucibles are suggested.
