Boron Nitride Rod, BN Rod

We provide standard and customised products for hot-pressed boron nitride rods. In addition to pure BN99 bars, we also supply BN composites with silicon carbide, calcium borate, aluminium nitride and zirconium oxide to meet different customer requirements. Please check the specifications of boron nitride for BN99 pure rods and ZSBN zirconium composite material.

As a supplier of solid advanced ceramic materials, heegermaterials Industries can customize all types of rods and other products with a MOQ of $300. Typical diameters of boron nitride rod is less than 12 x 15 inches due to the limitations of our equipment. Various types of machined boron nitride products are available based on drawings.

Advantages and applications of boron nitride rods:

Boron nitride ceramics from heegermaterialsIndustries Ceramics Division withstand high temperatures in high vacuum environments and have excellent corrosion and electrical resistance.

-Low wettability for molten metal.

-Relatively high thermal conductivity with low thermal expansion

-Relatively high heat resistance

-Exceptionally high operating temperature with suitable shielding gas (>3000C).

The above properties make boron nitride rod an ideal choice for a wide range of industries, e.g:

-steam vessels

-blowers for the non-ferrous metallurgical industry

-electrical insulators in vacuum systems

-insulators for high temperature furnaces

-removers for glass melting
