a.Why might a single crystal ceramic material have different coefficients of linear expansion depending on the crystallographic direction (anisotropy)?

b. In metals, thermal expansion and electrical conductivity may be related using equation the Weidemann-Franz law. Why is it possible to relate these two phenomena in this way for metals and why does this relation not hold for ceramic and polymeric materials?
