A hypothrtical AX type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. The atomic weights of the A and X elements are 28.5 and 30.0 g/mol, respectively. On the basis of this information, which of the following crystal structures is (are) possible for this material:

a. sodium chloride,
b. cesium chloride, or
c. zinc blende

Answer:

C. Zinc Blende

Explanation:

Out of the three possible crystal structures, only Zinc Blends is the unit cell structures which have four formula. Units per unit cell.

Therefore Zinc Blende is the only possible unit structures of AX ceramic material.
