As starting material for boron nitride ceramic
Thermally conductive material:
The high thermal conductivity, high filling density and low dielectric constant make hBN an ideal material for the production of thermal paste, thermally conductive plastic and printed circuit boards.
High temperature solid lubricant:
The graphite-like hexagonal modification (α-boron nitride) is used as a lubricant ("inorganic" or "white graphite"). In contrast to graphite, the friction coefficient of hexagonal boron nitride remains stable up to more than 1000 ° C, which is why it is very well suited as a high-temperature solid lubricant under vacuum.
Water treatment or purification:
A porous sponge of boron nitride is capable of absorbing about 33 times its own weight in oil and organic solvents. After burning or evaporation of the absorbed liquids, the filter sponge can be recovered unchanged. This property can be used for water treatment or purification
