Silicon carbide, SiC, has the three-dimensional structure shown in the figure.
(a) Name another compound that has the same structure.
(b) Would you expect the bonding in SiC to be predominantly ionic, metallic, or covalent?
(c) How do the bonding and structure of SiC lead to its high thermal stability (to 2700 °C) and exceptional hardness?
