Boron nitride, formula BN, is the binary compound, made up of boron and nitrogen in the same proportions, which presents interesting properties in the industrial field. Hexagonal boron nitride ceramics have excellent chemical, electrical, mechanical and thermal properties. They are widely used in sectors that require high-performance ceramics that have excellent characteristics in extreme conditions.
It is possible to provide composite boron nitride solutions for customers requiring specific characteristics, combining the properties of hBN with the desired properties of the specific ceramic additive, to produce a hybrid material that maintains the advantage of easy processability.
Ideal material for electrical insulators for high temperature and high voltage vacuum furnaces, metal crucibles, refractory elements, thermocouple protection tubes, rollers for glass and molten metal production, drawing supports, heat dissipation and insulating parts of semiconductors, melting nozzles for non-ferrous metals, channel components and pumps for molten metals.

CHEMICAL-PHYSICAL PROPERTIES
The fields of use of boron nitride are multiple, thanks to a series of chemical-physical properties that make this material suitable for various applications. Its main features are:
- Excellent dielectric properties (can be used as an electrical insulator)
- High operating temperatures in an inert atmosphere or vacuum, not exceeding 900°C in an oxidizing atmosphere, combined with good resistance to corrosion, due to its chemical stability, which makes it suitable for use in both acidic and alkaline environments
- Low conductivity and thermal expansion resulting in excellent resistance to thermal shock
- Easy workability: it can be worked according to the need to obtain the required shape and size
- It is not wetted by most metals and molten slag and can therefore be used as a container for most melt pools
The negative characteristics are fragility and low wear resistance.
