Description

Boron and nitrogen are neighbours of carbon in the Periodic Table. Just as carbon can exist as graphite (hexagonal) or diamond (cubic), boron nitride has both cubic and hexagonal forms and can be produced as nanotubes with a similar structure to carbon nanotubes. The most stable form of boron nitride is hexagonal boron nitride (h-BN). It also happens to be the softest of the BN polymorphs. Also known as white graphene, hexagonal boron nitride has a layered structure similar to graphite. Hexotene is a few-layer hexagonal boron nitride (h-BN) nanoplatelet powder with large lateral dimensions. With high chemical purity and mono-layer particles confirmed, Hexotene is the latest addition to our high performance 2D product range. It’s unique characteristics, specifically with regards to electrical conductivity, show some markedly different properties when compared to graphene. This is particularly promising for combined projects using both graphene and boron nitride. It is a good lubricant-at high and low temperatures (up to 900 °C) and in a vacuum.
