Application

Boron nitride has been well studied for applications including ceramic and polymer nanocomposites. Nanoscale boron nitride is essential for applications at this length scale as the increased surface area resulting in better incorporation in the matrix. BN possesses a number of material properties which increase its utility in machining and coating applications including wear resistance; chemical and thermal stability and wide band gap.
