Product Description

Product Description

BN ceramic Sleeve Custom

BN ceramic parts provide excellent high-frequency electrical insulation with low dielectric constant and ultra-low dielectric loss, effectively preventing current leakage, electric breakdown and signal interference under high-voltage working conditions.

Introduction on Boron Nitride Ceramics

Our BN (Boron Nitride) ceramic parts are high-performance industrial ceramic components featured with excellent thermal conductivity and ultra-high insulation properties. Adopting advanced hot-press sintering technology, these boron nitride ceramic components stand out from traditional alumina ceramics and plastic insulators, featuring low dielectric loss, high temperature resistance and stable chemical inertness. They are widely used in high-temperature equipment, high-frequency electronic devices, semiconductor industry and precision electrical insulation systems.

 

Our BN (Boron Nitride) ceramic parts feature premium pure BN material with low density, zero water absorption and ultra-dense uniform microstructure, delivering outstanding chemical stability, oxidation resistance and corrosion resistance for long-term service in harsh industrial environments. With ultra-high thermal conductivity and extremely low thermal expansion coefficient, these ceramic components withstand continuous high-temperature operation over 1000℃ and frequent cold-hot cycling. They maintain complete structural integrity without cracking or deformation, ensuring reliable and stable thermal performance for high-temperature equipment, semiconductor devices and high-end electronic systems.

Boron Nitride Ceramic Key Features 

1. Outstanding high temperature resistance, continuous service temperature up to 800℃ in air, stable performance under inert atmosphere

 

2. Excellent electrical insulation, low dielectric constant, good breakdown resistance

 

3. Natural self-lubricating property, no additional lubricant required

 

4. Good thermal shock resistance, low thermal expansion coefficient

 

5. Inert to most molten metals, acid and alkali corrosion resistance

 

6. Low outgassing rate, suitable for high vacuum working environment

 

7. Easy machining, customizable thread specification, size and shape
