why is the linear coefficient of thermal expansion in polymers greater than that of ceramic?

Expert Solution

Linear coefficient of thermal expansion of polymers greater than ceramics .So whatever amount of heat they absorb from surrounding or any other source, most of them is used in increasing interatomic distance rather than increasing the temperature of the polymer.The highest values in polymers are found among linear and branched polymers as they can expand more because of the lack of large number of intercrossing. other good reason can be because of the following fact: polymers are covalently bonded material and ceramic are ionic bonded material.covalent bonds do not let atoms exchange electrons like ionic bonds do.

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?
