Boron Nitride Rod
Dimensions: Length: 10~400mm, ID: >2mm
Boron Nitride Rods (HBN Ceramic Rods) – High-Temperature & Corrosion-Resistant
Boron nitride (HBN) ceramic rods offer exceptional high-temperature performance, with a working temperature of up to 1800°C in vacuum and 2100°C under inert gas. They also provide excellent acid and alkali corrosion resistance and high electrical insulation, with breakdown resistance 3-4 times higher than alumina ceramics.
Available in Various Sizes – Edgetech Industries supplies precision-engineered boron nitride rods tailored to your specifications.

Boron Nitride Rod characteristics
– Boron nitride ceramics have excellent thermal shock resistance. They will not crack after being rapidly cooled from 1000 degrees for 15 minutes to room temperature 100 times
– The oxidation resistance temperature is 1000 degrees, and it can replace graphite
– Resistant to metal corrosion and non-melting
– The product has high density, high mechanical strength, and good chemical stability
Applications of Boron Nitride Rods
– Electrical insulators in vacuum systems
– High-temperature furnace support components
– Ion implantation equipment
– High-voltage equipment components
– High-temperature electrical insulation components
Packing of BN Ceramics
As a ceramic material, boron nitride is quite fragile in a lot of cases. Our 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.
