What is the Silicon Nitride used for?

Silicon Nitride.

Silicon nitride has an organic chemical composition with Si3N4. It is an important structural ceramic with high hardness. The material can also resist shock and heat. It can be heated to greater than 1000 degrees Fahrenheit in the atmosphere. 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 hard heat can help improve the quality of diesel engines as well as save fuel.

For what purpose is Silicon Nitride?

Silicon nitride serves as a high quality refractory material. 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 of silicon nitride are extremely stable in temperature, resistant to oxidation and have 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 cannot be infiltrated or damaged by many molten alloys or metals. This includes aluminum, lead or silver as well as nickel and brass. However, it can be corroded or infiltrated with molten liquids like nickel-chromium alliance, magnesium, stainless steel, and even stainless steel.


These ceramic materials from silicon nitride are suitable for use in high temperature engineering components and advanced refractory materials within metallurgical and chemical industries.


The strong bonds that silicon nitride makes with aluminum oxide (silicon carbide), silicon carbide, thorium dioxide and silicon carbide can make it a versatile bonding 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, during the process of deposition of silicon nitride, the hydrogen atoms in the reaction product are introduced into silicon nitride wafer and the silicon movie. 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.
