Silicon Nitride Substrates

The following is the introduction of high quality Silicon Nitride Substrates, hoping to help you better understand it. Welcome new and old customers to continue to cooperate with us to create a better future! Their extremely high strength also makes them a key material that increases the life and reliability of the products they are used in. What is Silicon Nitride Substrates used for?Applications of silicon nitride ceramics include seal rings, bearing and sealing technology, etc. The combination of good tribological properties and excellent fracture toughness makes silicon nitride ceramics predestined for some applications.
