Silicon nitride has an inorganic chemical composition with Si3N4. It is an important structural ceramic with high hardness. The material can also withstand the heat and chill shocks. 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 temperatures and can transfer heat well, will 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. For example, SI3N4 SIC refractory is combined with sic. 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 ceramic have excellent thermal stability, excellent oxidation resistance, high product dimensions and high accuracy. 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 or thorium dioxide, boron and thorium nitride etc. allows it to be used as an adhesive 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 deposition, the hydrogen molecules of the reaction product are released into the silicon nanorode and silicon wafer. These acted as passivation defect. However, this atomic relationship of silicon silicon nitride with silicon nitride does not necessarily equal 4:3. This range fluctuates according to process conditions. Also, different physical properties of the films that correspond to different atomic relationships are affected.
