Product information "Min. 98.0% hexagonal boron nitride α-BN, approx. 1 µm, HBN, white, boron nitride, CAS No. 10043-11-5"
Hexagonal boron nitride, or h-BN for short, is a high-performance inorganic material made of boron and nitrogen. The material has a characteristic hexagonal crystal structure and, due to its white appearance and layered structure, is often referred to as white graphite. Like graphite, hexagonal boron nitride exhibits excellent lubricity and can be used as a functional material in many technical applications.
A significant advantage of h-BN is its high thermal and chemical stability. The material is suitable for applications at high temperatures and under demanding environmental conditions.
Furthermore, hexagonal boron nitride is characterized by low wettability with many melts, good thermal shock resistance, and excellent electrical insulation properties. Depending on its purity, grain size, and processing form, h-BN can be used as a powder, coating, molded body, or component of ceramic materials. General Applications of Hexagonal Boron Nitride Due to its versatile properties, hexagonal boron nitride is used in numerous industries. In the aerospace industry, h-BN is used, among other things, as a temperature-resistant material and for thermal and electrical insulation. Hexagonal boron nitride also plays an important role in the electronics industry because it can dissipate heat while simultaneously acting as an electrical insulator. This makes the material suitable, for example, for thermally stressed insulation components and applications in modern semiconductor technologies. In the ceramics industry, h-BN is used to produce high-performance ceramics, refractory materials, and temperature-resistant components. Its low wettability to molten glass and metal also makes hexagonal boron nitride a suitable high-temperature mold release agent. It is used, for example, in the casting and processing of glass, as well as in other thermal manufacturing processes. h-BN offers a practical alternative for applications where a clean separation between the workpiece and the mold is required. The properties of platinum cannot, of course, be fully achieved.Hexagonal boron nitride in nanotechnology and semiconductor technology
Hexagonal boron nitride is also used in nanotechnology and in the development of modern semiconductor devices. Its electrical insulation, thermal stability, and layered material structure make h-BN interesting for various research and industrial applications. Particularly with suitable material quality, hexagonal boron nitride can be used as a component of coatings, insulating layers, and special ceramic composites.
In particularly pure and appropriately tested quality, h-BN can also be of interest for biomedical applications.
However, suitability for implants, prostheses, or other medical products always depends on the specific purity, processing, material quality, and approval. The hexagonal boron nitride we supply is of technical grade and is therefore primarily intended for industrial, technical, and commercial applications. Technical Boron Nitride for Demanding Applications Our hexagonal boron nitride (h-BN) is suitable for numerous applications where a combination of temperature resistance, electrical insulation, chemical stability, and good release properties is required. Whether as a raw material for ceramic products, as a component of technical coatings, as a high-temperature mold release agent, or for applications in the electronics and semiconductor industries – h-BN is a versatile material for demanding industrial processes.

Molybdenum disulfide is a naturally occurring mineral, referred to in its natural form as molybdenite or jordisite. Its excellent lubricating properties are based on its layered molecular structure. Strong atomic bonds form exclusively within the atomic layers, while significantly weaker van der Waals forces exist between those layers. This results in very easy sliding of the individual planes, which can also be observed in graphite.Due to its high effectiveness, approximately 1.0 kg of grease (or about 800–900 ml of lubricating paste) can be produced with just 100 g of MoS2. In gear oils, the proportion is often less than 1%. However, in machine suspensions these proportions can vary considerably. Molybdenum disulfide is a widely used dry lubricant in mechanical engineering. The very soft material adheres particularly well to steel and various metals, making it a durable functional material. The applied film is thermally stable up to approximately 350°C or 450°C and exhibits significant resistance to water and most acids.

Tungsten disulfide (tungsten(IV) sulfide, WS2) is, similar to our hexagonal boron nitride, molybdenum disulfide, graphite, and PTFE (Teflon), an excellent dry lubricant. However, it exhibits improved physical properties compared to the substances mentioned. It adheres significantly more easily to metallic surfaces, has a high temperature resistance and is chemically inert. Some older combustion engines and engines with a special design burn a certain amount of oil. Should tungsten disulfide be used as an additive for this purpose, it should be noted that this can cause significant combustion residues and thus damage.

This copper powthe is specially designed for optical and functional applicationsdeveloped and manufactured worden. This is pure copper, which has been stabilized with 1,5 % oleic acid. In Kunststoffverarbeitung produces outstanding effects in HDPE, LDPE,ABS othe gar PVC. In this context should during the Fertigung of Masterbatches care must be taken to ensure that the powthe nur geringstmöglichen Scherkräften and Verweildauern during hohen Temperaturen ausgesetzt wird. Beide Faktoren könnten sonst the optical Endergebnis negativ beeinflussen. Ebenfalls is this powthe bestens auf den Einsatz in paints/coatings/2K-Harz and screen-printing processes abgestimmt. A ratio of 5/100 (Pigment/Bindemittel) is for ein optisch high-quality result . This produces an impressive copper-metallic effect - the surface sieht anschließend wie ein polished copper sheet aus. Bitte beachten Sie during the processing: screen printing: Maschenweite should drei mal größer als the D90-Wert des powders sein. Aerosol spray cans: Der D90-Wert des powders sollten mindestens drei mal kleiner als the Düsendurchmesser sein. Lacke/paints: Mechanische Einflüsse durch sehr schnell drehende agitators avoid. Dies würde the Partikel beschädigen and den Metallic-Effekt zerstören.
