Borazon is a brand name of a cubic form of boron nitride (cBN). Its color ranges from black to brown and gold. It is one of the hardest known materials, along with various forms of diamond and other kinds of boron nitride. Borazon is a crystal created by heating equal quantities of boron and nitrogen at temperatures greater than 1800 °C (3300 °F) at 7 GPa (1 million lbf/in2).

They are frequently used to remove pollutants and in the cleanup of chemical accidents and oil spills. Besides their uses in industry, sorbents are used in commercial products such as diapers and odor absorbents, and are researched for applications in environmental air analysis, particularly in the analysis of volatile organic compounds. The name sorbent is derived from sorption, which is itself a derivation from adsorption and absorp
