Boron Nitride Tubes and Rods

Product Description

General Description:

Material: Boron nitride tubes and rods are primarily composed of boron nitride, which can exist in different crystalline forms, including hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN). These forms have varying properties and applications.

Manufacturing Process: Boron nitride tubes and rods are typically manufactured through processes such as hot-pressing or extrusion.

1. • Hot-pressing: In this process, boron nitride powder is compacted under high temperature and pressure to form a solid structure. The hot-pressed material is then further processed to obtain the desired tube or rod shape.
   • Extrusion: Boron nitride powder mixed with binders is forced through a die to form the desired shape. The extruded structure is then heated to remove the binders and sintered to achieve the final boron nitride product.

This material can easily be machined to close tolerances in virtually any shape. Under an inert and reducing atmosphere, Boron Nitride can withstand temperatures over 2000°C.

Dimensions: Boron nitride tubes are hollow cylindrical structures with varying inner and outer diameters, wall thicknesses, and lengths. Boron nitride rods, on the other hand, are solid cylindrical structures with uniform diameters and lengths. The dimensions of boron nitride tubes and rods can be customized according to specific requirements.

Boron nitride tubes and rods can be customized with features such as flanges, threads, or connectors to facilitate installation and connections in specific applications.

It’s important to note that the specific properties and dimensions of boron nitride tubes and rods can vary based on the manufacturer and the intended application. Therefore, it’s advisable to consult M-Kube team for detailed specifications and recommendations based on your specific needs.
