One form of silicon carbide,SiC,is an extremely hard solid that melts at 2730 $\circ$ C and diffracts X-rays.What type of solid is this form of SiC?

Question

Quizplus · Accepted Answer

Silicon carbide form with the given properties is a network covalent solid, where the Si and C atoms are covalently bonded in a continuous network in three dimensions. This results in a strong and hard material with high melting and boiling points, which can diffract X-rays due to its regular arrangement of atoms in the crystal lattice.
