摘要：

Moments of momentum (MoM) calculations using chemical species expected to exist in the melts from which crystals of YBa2Cu3O7-x grow predict some of the same crystal habits as found by the periodic bond chain method. Since momentum methods utilize solution species and their distributions, the results provide insight as to species in the melt that are potential precursors to actual crystal growth. Whether copper (II) oxide is present as a square planar or square pyramidal complex in the melt affects the crystal habit with the latter complex suppressing the appearance of {010} faces.
