Question 25

An industrial smelting crucible is lined with magnesium oxide ( $M g O$ ), which has a melting point of $2852∘C2852^{\circ}\text{C}$ .

Explain, in terms of structure and bonding, why magnesium oxide has such a high melting point and is therefore suitable for this high-temperature application.
