An economical solution to h-BN exfoliation. h-BN flakes powders come in large quantities (see images), and can be exfoliated onto arbitrary substrates on multiple occations (+10000 times) to be used for years. This product contains small crystallites of h-BN layered flakes that can be used for conventional exfoliation process as well as liquid phase h-BN solution manufacturing. Exfoliation from h-BN flakes produces atomically flat (see product images) that are similar to exfoliation from bulk crystals. 
 
hBN flakes have ~2000-10000 defects/per unit cell, and possess ~6-7cm-1 FWHM Raman broadening. Raman spectrum matches well to the published data in the literature. 
 
Typical product is projected to be sufficient for more than a year. This product contains one full capsule of hBN flakes.
