ZSBN Nozzle,Boron Nitride Composite Ceramic

Product Code : CE-BN-5N-CER

Boron Nitride is an advanced synthetic ceramic material available in solid and powder form. Its unique properties – from high heat capacity and outstanding thermal conductivity to easy machinability, lubricity, low dielectric constant, and superior dielectric strength – make boron nitride a truly outstanding material. In its solid form, boron nitride is often referred to as “white graphite” because it has a microstructure similar to that of graphite. However, unlike graphite, boron nitride is an excellent electrical insulator that has a higher oxidation temperature. It offers high thermal conductivity and good thermal shock resistance and can be easily machined to close tolerances in virtually any shape. After machining, it is ready for use without additional heat treating or firing operations.

We provide standard products & tailor-made products for hot-pressed boron nitride Nozzle. Except for pure BN99 plates & sheets, we also supply BN composites with silicon carbide, calcium borate, aluminum nitride, and zirconia, to fulfill various demands of the customers

Boron nitride composite ceramic ZSBN, using carbide and zirconia as bonding agents, improves the thermal shock resistance and wear resistance of the merchandise. It's commonly used as a separate ring for horizontal continuous casting and a nozzle made from an amorphous ribbon. These products have stable chemical properties, high thermal shock resistance, and high corrosion resistance. they're widely utilized in molten metal contact.

Applications of Boron Nitride Nozzle

 

Packing of Boron Nitride Nozzle

Standard Packing:

Sealed bags in carton boxes. Special package is available on request.

As a ceramic material, BN is quite fragile in a lot of cases. The BN Nozzle are usually held in plastic bags by vacuum, and protected with heavy foam.

ATTs’ BN Nozzle is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
