Silicon Nitride Ceramic Parts
Material: Silicon Nitride，Ceramic
Shape: Support Customization
Shanghai Metal Corporation is a leading Silicon Nitride Ceramic Parts manufacturer and supplier.
Silicon nitride ceramics, an inorganic material ceramic that does not shrink when sintered. Silicon nitride (Si3N4) has an outstanding combination of material properties. Its low density, its own hardness, and because of the special crystal structure gives it excellent thermal stability and high fracture toughness performance, becoming a better choice for use in extreme conditions. Therefore, silicon nitride ceramics is an excellent choice for high-speed and high-precision bearings, as well as an important material for high-temperature molding, high-speed cutting tools and high-temperature wear-resistant parts. Meanwhile, in the aerospace field, it is also the best material for radar antenna devices and engines. As long as you can provide design drawings, our company can customize various shapes of silicon nitride ceramic parts for you.
If you want to know more about it, please feel free to contact us. We will reply you within 24 hours.
Packaging of Silicon Nitride Ceramic Parts
Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.
1) Shanghai Metal Standard
2) Customization
Process method:
Silicon nitride ceramics are made of silicon powder as raw material, first made into the desired shape by the usual molding method, and then nitrided initially in nitrogen and at a high temperature of 1200°C, so that part of the silicon powder reacts with nitrogen to generate silicon nitride, at which time the whole billet already has a certain degree of strength. Then in the 1350 ℃ ~ 1450 ℃ high temperature furnace for the second nitriding, reaction into silicon nitride. With the hot press sintering method can be produced to reach the theoretical density of 99% of the silicon nitride.
