Crystal Lattices and Unit Cell

Consider a crystal. The regular and repeating pattern of constituent particles is the most distinguishing feature of crystalline solids. A crystal lattice is formed when these particles are replaced with representative points. The three-dimensional arran…

Textbook Question

Chapter 10, Problem 87E

Materials containing the elements Y, Ba, Cu, and O that are superconductors (electrical resistance equals zero) at temperatures above that of liquid nitrogen were recently discovered. The structures of these materials are based on the perovskite structure. Were they to have the ideal perovskite structure, the superconductor would have the structure shown in pant (a) of the following figure.

Chapter 10, Problem 87E, Materials containing the elements Y, Ba, Cu, and O that are superconductors (electrical resistance

a. What is the formula of this ideal perovskite material?

b. How is this structure related to the perovskite structure shown in Exercise 85?

These materials, however, do not act as superconductors unless they are deficient in oxygen. The structure of the actual superconducting phase appears to be that shown in pan (b) of the figure.

c. What is the formula of this material?
