Boron Compounds Ltd (BCL) produces hexagonal boron nitride (hBN) powders in amorphous and crystalline (hexagonal, turbostratic) structures in sub-micron and nano-particle sizes. The hexagonal form is the most stable and softest boron nitride polymorph, making it well suited for use as a lubricant and as an additive in cosmetic products. The company's products can also be used in high-heat environments and formed into cubes that are almost as hard as diamonds. The company's boron nitride powders are available in four physical configurations, each with differing particle and crystal sizes.
