300mm diameter boron nitride ceramic bushing

The 300mm diameter boron nitride ceramic bushing is a high-performance ceramic component, which is made of high-purity boron nitride (BN) material, and has excellent high temperature resistance, corrosion resistance, insulation and self-lubricating properties. This bushing is specially designed for extreme working conditions, and is suitable for high temperature, high pressure and strong corrosive environments. It can effectively replace traditional metal or ordinary ceramic bushings, significantly improving equipment life and operating stability.
Key characteristics
-High temperature resistance: it can work stably in an environment above 1000 ° C for a long time, and can withstand temperature up to 1800 ° C in a short time.
-Low thermal expansion coefficient: excellent thermal stability, reducing the risk of deformation or cracking caused by temperature changes.
-Chemical inertia: It has strong resistance to most acids, alkalis, molten metals and corrosive gases.
-Self lubrication: low friction coefficient (0.2~0.4), reduce wear and prolong service life.
-High insulation: excellent electrical insulation performance, suitable for electronic, semiconductor and other industries.
-High mechanical strength: high compressive and bending strength, suitable for high-pressure environment.

Typical applications
300mm large-diameter boron nitride ceramic bushing is widely used in industrial fields that need high temperature resistance, corrosion resistance, high insulation or self-lubricating performance. The main application scenarios include:

1. Metallurgy and casting industry
   -It is used for the lining of conveying pipes and crucibles for molten metals (such as aluminum, copper and steel) to avoid metal adhesion or erosion.
   -As a guide part of continuous casting equipment, it can reduce the friction loss of high-temperature molten metal.
2. Semiconductor and photovoltaic industry
   -Heat insulation rings and supports for monocrystalline silicon and polycrystalline silicon growth furnaces to ensure stability and purity under high temperature environment.
   -As the insulation bushing of CVD (chemical vapor deposition) and PVD (physical vapor deposition) equipment, prevent pollution.
3. Chemical and energy industry
   -It is suitable for corrosive gas (such as chlorine and fluorine) transmission pipeline with excellent acid and alkali resistance.
   -It is used for high-temperature reaction kettle and electrode insulation parts to improve equipment safety.
4. Aerospace and high-end manufacturing
   -As an insulation component of rocket engine nozzle, it can withstand extreme high temperature and thermal shock.
   -It is used for high-precision mechanical bearing bush to reduce friction and improve operating efficiency.
