Cubic boron nitride produced by high temperature, high pressure processing is made of hexagonal boron nitride

Cubic boron nitride can be produced at high temperature, high pressure process from hexagonal boron nitride, as similar to the synthetic diamond from graphite. Directly into the hexagonal boron nitride CBN need 18 million Pa pressure and 1730-3230 ° C temperatures. Add a small abrasive wheels can be reduced to the desired pressure of 4 to 7 million Pa, the temperature dropped to 1500 ° C.
In industry, people using the catalytic conversion of boron, and Polycrystalline diamond material will be used in different production methods, such as lithium, platinum, or magnesium, and their nitrides, nitride, fluoride, water plus abrasive grinding or hydrazine. Other industrial synthesis method uses a temperature difference results from the crystal or the blast wave. Shock wave application is used to produce hard diamond called iso boron, carbon and nitrogen compounds.
Low pressure, cubic boron nitride thin films can be deposited technologies. In chemical vapor deposition, boron trifluoride can be used to selectively etch deposited hexagonal boron nitride. Other physical vapor deposition method such as ion beam deposition, plasma chemical vapor deposition to improve, pulsed laser deposition, reactive sputtering method, etc. are also used.
