Polvere di nitruro di boro esagonale al 99%

99% Hexagonal Boron Nitride Powder, commonly known as white graphite, is the most stable and commonly used crystal form of boron nitride, a graphite-like layered ceramic material. Our company produces cubic boron nitride using small-capacity, segmented, temperature-controlled continuous production to ensure complete boron nitride reaction, resulting in boron nitride products with low oxygen content, high purity, and good particle size control. Cubic boron nitride is mainly used in the production of various thermally conductive materials, high-temperature resistant products, and functional fillers.

Product Performance Advantages:

1. Good insulation: resistivity >10¹⁴ Ω・cm, non-conductive.
2. High thermal conductivity: high thermal conductivity, good heat dissipation.
3. High temperature resistance: the physicochemical properties of hexagonal boron nitride remain unchanged below 1000℃ at ambient temperature and at 3000℃ in nitrogen or argon atmosphere. Hexagonal boron nitride-H type powder, after hot pressing and sintering, becomes a white block, easy to process, and can withstand temperatures up to 2000℃.
4. Excellent lubrication performance: Low coefficient of friction (~0.16), no slagging or oxidation during high-temperature lubrication.
5. Chemical inertness: Resistant to acids and alkalis, corrosion resistant, relatively stable to almost all organic solvents and corrosive chemicals, and chemically inert to almost all molten metals.
6. Strong neutron absorption capacity.

Applications:

1. Moderately crystalline with excellent high-temperature resistance and oxidation resistance. Its initial particle size is small, but the aggregated particle size is large. Because the particles are spherical, it is particularly suitable as a filler, a release agent for casting and injection molding, and for composite ceramics. It is also easy to hot press.
2. The product’s performance reaches or approaches the advanced level of similar foreign products and can replace imported products. Due to its particle size being similar to that of polytetrafluoroethylene (PTFE) and its uniform particle size, it is particularly suitable for use as a high-voltage switch spray nozzle.
3. It has superior thermal conductivity, making it very suitable for use as a thermally conductive plastic or thermally conductive rubber.
4. Hexagonal boron nitride has a low oxygen content, making it particularly suitable as a raw material for special ceramics.
5. Il prodotto presenta un’elevata cristallinità e una granulometria più uniforme. Il nitruro di boro esagonale ad alta cristallinità mostra una conduttività termica, un isolamento, una lubrificazione, una resistenza alle alte temperature e una resistenza alla corrosione da metalli fusi superiori rispetto ai prodotti comuni. Può essere utilizzato in diversi settori di fascia alta, tra cui la cosmetica e i materiali termoconduttivi. Le sue prestazioni raggiungono o si avvicinano al livello avanzato di prodotti esteri simili e può sostituire i prodotti importati.
6. Ossigeno <0,3% <0,5% <5% <2% Il prodotto stesso ha un’elevata conduttività termica, isolamento elettrico, bassa costante dielettrica, basso coefficiente di espansione e buona stabilità, pertanto è spesso utilizzato come additivo nell’industria elettronica di fascia alta.
