What characteristics of silicon nitride risers are widely used- Zhejiang Shangguijuli Special Material Technology Co., Ltd.

Silicon nitride riser tube are a key component widely used in high-performance industrial applications. Their unique physical and chemical properties enable them to perform well in multiple industries.

First, the high-temperature stability of silicon nitride is one of its most notable features. This material can maintain structural stability and unchanged performance under extremely high temperature conditions, and can usually withstand temperatures of thousands of degrees Celsius. In the metal casting industry, silicon nitride risers are widely used as gate tubes or pouring tubes, which can withstand the high temperature and pressure of liquid metal to ensure the stability of the casting process and product quality.

Secondly, silicon nitride has excellent mechanical properties. It not only has high strength and hardness, but also has high bending strength and compressive strength. These characteristics enable silicon nitride risers to operate stably for a long time under high pressure and mechanical stress, and are not prone to deformation or wear, which is crucial for semiconductor furnace tubes or high-temperature reaction devices that operate for a long period of time.

Chemical stability is another major advantage of silicon nitride. It exhibits excellent resistance to corrosive media such as acids and alkalis, which makes silicon nitride risers widely used as corrosion-resistant pipes or protective sleeves in the chemical and metallurgical industries. When dealing with corrosive media or high-temperature reaction environments, the stability and durability of silicon nitride are much better than traditional materials.

Silicon nitride has good thermal conductivity, even though it is an insulating material. This material can effectively transmit and disperse heat, which is particularly important in semiconductor manufacturing. In the application of high-temperature furnace tubes or protective tubes, good thermal conductivity helps to maintain a stable temperature of the equipment and ensure the reliability and accuracy of the production process.

The low thermal expansion coefficient of silicon nitride is also one of its important characteristics in high-temperature applications. Compared with metals, silicon nitride has a lower thermal expansion coefficient, which means that its size changes less when the temperature changes, which helps to maintain the stability and accuracy of the process, especially in precision industrial manufacturing.
