Boron Nitride Rod (BN Rod)
We provide standard products & tailor-made products for hot-pressed boron nitride rod. Except for pure BN99 rods, we also supply BN composites with silicon carbide, calcium borate, aluminum nitride and zirconia, to fulfill various of demand for the customers. Check the boron nitride specifications for our pure BN99 and zirconia composite material ZSBN.
As a supplier of solid advanced ceramic materials, Edgetech Industries can tailor-make all kinds of rods and other products with $300 MOQ. Typical boron nitride rods are smaller than 12″ dia. x 15″ length due to the limitation of our equipment. Other form of boron nitride machined products could be available with drawings.

Boron Nitride Rod Advantages & Applications:
Boron Nitride ceramic from Edgetech Industries Ceramics Division can withstand high temperature in the high vacuum environment, plus it has excellent corrosion resistance and electrical resistance.
-Low wettability to molten metal
-Relatively high thermal conductivity with low thermal expansion
-Relatively high thermal shock resistance
-Extremely high working temperature with proper inert gas protection (>3000C has been recorded).
Based on the above properties, Boron Nitride Rod is an ideal choice in a wide range of industries, such as:
-Nozzles for nonferrous metals metallurgy industry
-Electric insulators in the vacuum system
-Insulators for high-temperature furnace
-Spacers for glass melting
As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Rod is carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for BN products, vacuum packing is also engaged for some of the parts.
