What is the difference between hexagonal boron nitride and cubic boron nitride

There are four types of boron nitride, hexagonal boron nitride, rhomboid boron nitride, cubic boron nitride and wurtzite boron nitride. It’s easy to confuse hexagonal boron nitride with cubic boron nitride. What’s the difference between hexagonal boron nitride and cubic boron nitride?
The difference between hexagonal boron nitride and cubic boron nitride lies in their different physical structures and USES.
Boron nitride is a kind of white crystal, stable chemical property, high temperature resistance, melting point up to 3000 degrees Celsius, strong acid corrosion resistance, good electrical insulation, excellent high temperature lubrication. Because the structure and graphite similar, often known as white stone ink, white stone ink is the simplest boron nitrogen macromolecule, hexagon boron nitride nitrogen and boron also form hexagonal network layer, overlap each other, constitute a crystal. The crystal is similar to graphite in diamagnetism and anisotropy.
Cubic boron nitride (CBN) is a new synthetic material developed in the 1950s, characterized by high hardness and good wear resistance. Cubic boron nitride is often used in abrasive and cutting tool materials, which are sensitive to local thermal stress and thermal impact of various materials parts grinding
