Boron nitride ceramic ring sleeve

Boron nitride ceramic ring sleeve is a high-performance engineering ceramic component made by sintering high-purity boron nitride (BN) material through advanced technology. Boron nitride ceramics have excellent high temperature resistance, chemical stability, electrical insulation, and lubrication properties, enabling them to maintain stable physical and chemical properties even in extreme environments.

Main characteristics
-High temperature resistance: Can be used for a long time in high temperature environments above 1000 ° C, and can withstand high temperatures of 1800 ° C in the short term.
-Low thermal expansion coefficient: Excellent thermal stability, reducing deformation caused by temperature changes.
-Excellent electrical insulation: high resistivity, suitable for high-voltage and high-frequency electronic equipment.
-Chemical inertness: Resistant to acid and alkali corrosion, does not react with most molten metals, glass, and salts.
-Self lubrication: Low friction coefficient, similar to graphite, suitable for high wear environments.
-Mechanical processing performance: It can be precision machined into complex shapes to meet different application requirements.
Boron nitride ceramic ring sleeves can be provided with products of different purities (such as high-purity BN above 99%), different structures (such as open rings, closed rings, irregular rings, etc.), and different size specifications according to customer needs.

Application Fields
Boron nitride ceramic ring sleeves are widely used in the following industries due to their unique properties:

1. Semiconductor and Electronics Industry
   -Crystal growth equipment: used for growth crucibles and thermal field components of semiconductor materials such as monocrystalline silicon and gallium arsenide.
   -Electronic packaging: used as a high thermal conductivity insulation gasket for power modules and LED heat dissipation.
   -Plasma equipment: used for RF windows, insulation rings, etc., resistant to plasma erosion.
2. Metallurgy and Glass Industry
   -Metal melting: As a crucible lining for melting metals such as aluminum, magnesium, copper, etc., it prevents metal contamination.
   -Glass molding: used for glass molds and guide rollers to avoid high-temperature adhesion.
3. Aerospace and high-temperature furnaces
   -Rocket nozzle: resistant to high temperature erosion, suitable for aerospace propulsion systems.
   -Vacuum furnace insulation: As an insulation ring and support for high-temperature furnaces, it reduces heat loss.
4. Chemical and mechanical seals
   -Corrosion resistant sealing ring: used for sealing pumps and valves in strong acid and alkali environments.
   -Bearings and guides: provide low friction operation in oil-free lubrication environment.
5. Research and Special Applications
   -Nuclear industry: as neutron absorbing materials and high-temperature reactor components.
   -Laser equipment: used for the reflector base and heat dissipation components of high-energy lasers.
