Question:

The table below contains conductivity data for two materials. The melting point of PbF₂ is 1103 K.

(a) Describe the structure of each material and the origin of the relatively high conductivities.

(b) Comment on the temperature dependence of conductivities.

(c) For Zr_1−xY_xO_2−x/2, estimate the activation energy for charge-carrier migration. State two possible uses of Zr_1−xY_xO_2−x/2.

T(K) 670 840 1250 PbF0 (S/cm) 0.1 4.6 4.6 Zr-xYxO-x/20 (S/cm) 0.0001 0.002 0.1
