BN Boron Nitride Ceramic Structural Parts

Design Features
Boron nitride ceramic tube sleeves (also known as ceramic structural rings) are high-performance ceramic materials primarily used in industrial applications requiring high temperature, high pressure, and excellent electrical insulation properties. Their main characteristics and application areas are as follows:

High-Temperature Stability

Boron nitride ceramics can maintain their structure and performance at extremely high temperatures (up to 850°C in air and 2000°C in inert gases), making them suitable for high-temperature environments.

Excellent Electrical Insulation

Boron nitride offers outstanding electrical insulation, with a room temperature resistivity of up to 10^16 Ω·cm, ensuring safety in electrical applications.

Superior Thermal Conductivity

With high thermal conductivity (50-70 W/(m·K)), boron nitride is ideal for use in thermal management systems to optimize the thermal performance of equipment.

Low Thermal Expansion Coefficient

Boron nitride has a low thermal expansion coefficient (1-1.2 x 10^-6/K), maintaining dimensional stability in thermal cycling applications and reducing thermal stress issues.

Chemical Inertness

Boron nitride is highly resistant to most chemicals and corrosive environments, ensuring performance is not affected in harsh conditions.

Self-Lubricating Properties

Hexagonal boron nitride possesses a degree of lubricity, making it suitable for mechanical applications that require a low friction coefficient.
