Boron nitride is an extremely versatile material and is available in several different forms, depending on the industrial application.
The most important forms include:
- Solid Form (Sintered Components): In its solid form, boron nitride is often referred to as “white graphite” due to its structure. The material is hot-pressed under high pressure and temperature into large blocks or billets, from which high-precision and complex components are subsequently manufactured. At Henze BNP, these thermally conductive and electrically insulating components are known under the HeBoSint® product family.
- Powder Form: Boron nitride powders are available in a wide range of grades and are primarily used as functional fillers. They are used, for example, to make plastics thermally conductive (thermal management) or as solid lubricants. These powder products are available from Henze under the brand name HeBoFill®.
- Liquid Form (Coatings / Suspensions): Boron nitride is used as a water- or solvent-based liquid suspension to apply or coat surfaces. This provides excellent release and lubrication properties, e.g., in metal casting. These coatings are part of the HeBoCoat® product family.
- Aerosol form (sprays): For particularly easy, quick, and precise application, boron nitride is also available as a spray. This is ideal for pressure sintering on small surfaces or for protecting welding and brazing fixtures. At Henze, sprays are also part of the HeBoCoat® product group (Spray Line).
- Lubricant additive (oil dispersion): In this form, ultra-fine boron nitride particles are present in a highly concentrated and finely dispersed state within an oil. When used as an additive in conventional lubricants, it has been proven to minimize friction and wear in engines and transmissions. This liquid additive is marketed under the name HeBoLub®.
