1.For a ternary system, three components are present; temperature is also a variable. What is the maximum number of phases that may be present for a ternary system, assuming that pressure is held constant?

2.The surface energy of a single crystal depends on crystallographic orientation. Does this surface energy increase or decrease with an increase in planar density? Why?

3.What point defects are possible for MgO as an impurity in Al2O3? How many Mg2+ ions must be added to form each of these defects?

4.Can Schottky defects exist in K2O? If so, briefly describe this type of defect. If they cannot exist, then explain why?
