Graphite powder BT40, carbon min. 99.6%, 7782-42-5, pure, synthetic, anthracite, super fine powder

Product information "Graphite powder BT40, carbon min. 99.6%, 7782-42-5, pure, synthetic, anthracite, super fine powder"

This synthetic graphite powder is produced by high-temperature graphitisation of carbonaceous precursors and is characterised by an exceptionally high carbon content of at least 99.6% and a fine, narrowly defined particle size distribution. Its pronounced crystalline layered structure, in which carbon atoms are arranged in hexagonal basal planes, confers excellent electrical and thermal conductivity. At the same time, the weak van der Waals interactions between adjacent layers allow them to slide readily over one another, which accounts for the material's characteristic lubricating properties.

The low ash content and minimal residual moisture reduce the influence of metallic and other impurities, thereby ensuring a high degree of reproducibility in demanding applications. The powder is particularly well suited to uses in which defined requirements regarding electrical conductivity and dispersibility within matrix systems must be met.

Frequently Asked Questions (Q&A)

How does synthetic graphite differ from natural graphite?

Synthetic graphite is produced industrially at temperatures above 2,500 °C and therefore generally offers higher purity and more consistent quality than mined natural graphite.

Can the powder replace molybdenum disulphide as a dry lubricant?

In many applications, yes. However, suitability depends on the specific operating conditions (e.g. atmosphere, temperature, load); preliminary testing is recommended.

What do the values D10, D50 and D90 mean?

They describe the particle size distribution: 10%, 50% and 90% of the particles (by volume) are smaller than the respective value stated. D50 corresponds to the median.

Is the material suitable for lithium-ion batteries?

The powder can be used as an anode material. Particle size, surface area and electrolyte compatibility should be assessed for each specific cell design.

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.

min. 98.5% molybdenum disulfide, molybdenum(IV) sulfide, MoS2, very fine 4–5 µm powder, CAS No.: 1317-33-5
pack size: 50g

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.
