What Type Of Crystal Is Boron Nitride?

There are four common crystal types in the field of boron nitride: ionic crystal, atomic crystal, molecular crystal and metal crystal.Ionic crystal is a topic that cations and anions are combined by ionic bonds. All atoms in atomic crystal are in a spatial network structure that is bonded by covalent bonds. Molecular crystal is a solid substance formed by intermolecular forces. Metal crystal refers to metal simple substance and alloy.What kind of crystal does boron nitride belong to?Boron nitride has high hardness, high temperature resistance of 2000℃, melting point of 3000℃ under nitrogen pressure, insolubility in cold water, slight solubility in hot acid, and so on.From the molecular structure point of view, the nitrogen atom and boron atom in BN are bound together by covalent bond. To sum up, boron nitride is an atomic crystal.
