摘要：
Lead metaniobate ceramics were tape cast with inclusions of acicular seed particles. The effects of seed particle concentration, slurry viscosity, and casting velocity on the shear behavior of the tape cast slurry were quantified based on a model using the ratio of pressure driven forces to viscous driven forces. Texture was quantified using a combination of X-ray diffraction with the Lotgering factor and neutron diffraction with Rietveld refinement. The shear behavior of the individual slurries was linked to the amount of texture that is induced from given slurry. (c) 2007 Elsevier Ltd. All rights reserved.
