What is the Silicon Nitride used for?

Silicon Nitride.

Silicon nitride has an inorganic chemical composition with Si3N4. It is an important structural ceramic with high hardness. The material can also resist shocks of heat and cold. It can be heated to greater than 1000 degrees Celsius in the air. If it is rapidly cool and heated again it does not break. The excellent properties of silicon-nitride ceramics is why it's often used in the manufacture of mechanical components, such as bearings. A silicon nitride-ceramics heat-receiving layer for engine components that is resistant to high heat and difficult to transmit heat can help improve the quality and efficiency of diesel engines.

For what purpose is Silicon Nitride?

Silicon nitride serves as a high quality refractory material. It can include SI3N4 SIC refractory and sic for blast furnace shaft. This fine-structure ceramic material is known for its uniformity and mechanical strength. It's also called the SI3N4BN-BN series horizontal continuously casting separation ring. The material meets continuous casting technology requirements and has excellent thermal shock resistance.


Materials made with silicon nitride clay have excellent thermal stability, resistance to oxidation, and high dimensions. Covalent compounds with high bond strength can create an oxide protective shield in the atmosphere. Silicon nitride also exhibits good chemical stability. It doesn't oxidize, so it won't be affected by any molten metals.


These ceramic materials from silicon nitride are suitable for use in high temperature engineering components, advanced and complex refractory materials, chemical industry corrosion-resistant, sealing and cutting components as well.


The strong bond that silicon nitride makes with aluminum oxide (silicon carbide), silicon carbide, thorium dioxide and silicon carbide can make it a versatile bond material.


You can use silicon nitride in solar cells. When the silicon nutride film has been coated with the PECVD procedure, it can serve as an antireflection film that reduces incident light. However, the reaction product's hydrogen atoms enter both the silicon nanorode and silicon wafer during deposition. These acted as passivation defect. However, this atomic relationship of silicon silicon nitride with silicon nitride does not necessarily equal 4:3. It is subject to fluctuations due to process conditions. Also, different physical properties of films that correspond to different atomic relationships can have different physical characteristics.
