Silicon Nitride has been discovered since the beginning of the 19th Century. However, it’s difficult to manufacture because of its covalent bonds. A type of engineering ceramic with excellent chemical and thermal stability, silicon nitride is high in strength and fracture toughness. The polycrystalline form of Silicon Nitride is a type of composite made of single crystals (silicon nitride) that are embedded in either amorphous, partially crystalline or crystalline glass phases. These properties are not dependent only on the inherent silicon nitride properties, but also on size and morphology, and volume fraction, and chemical properties, of the glass phase located at silicon-nitride grain borders. Si3N4 can be used for both traditional and more innovative applications. Si3N4 has many advantages, including its light weight, great bending strength and wear resistance, as well as being able to endure the most harsh environments.
Automobile industry.
The automotive sector is one of the most important uses of sintered silicone nitride. For example, there are electric plugs in diesel engines that provide faster start-up, precombustion chambers that produce less emissions, lower start-up, and more noise and turbochargers. For spark ignition engines silicon nitride helps reduce wear rocker pads and turbocharger turbines reduce engine lag. Exhaust control valves increase acceleration.
Bearing.
An all-ceramic silicon nitride bearing does not just have ceramic components, it also has a ceramic hybrid bearing. For example, the ceramic ball and steel seat rings are made of silicone nitride. The silicon nitride clays offer superior shock resistance to other ceramics. Ball bearings constructed from silicon nitride ceramics have high-performance bearings. NASA’s main engine uses silicon-nitride bearings. Because silicon nitride balls bearings are more durable than metal, they have less contact with bearing tracks. This is a better alternative to traditional metal bearings. They can lower friction by as much as 80%, improve service life by three to 10 times and increase speed by 80 percent. Silicium nitride is 79% lighter that tungsten caride balls. Silicon nitride can be used as a ball bearing in automobile bearings, high-end industrial bearings. Wind turbines. Racing sports. Bicycles. Roller skates. Skateboards. These bearings can be used in areas where metals cannot be used due to corrosion.
High-temperature material.
Since long, silicon nitride is used in high-temperature applications. Particularly, silicon nitride has been found to be one of only a few integral ceramic materials capable of withstanding severe thermal shocks as well as thermal gradients created by the hydrogen/oxygen rocket engines. NASA scientists employed advanced rapid prototyping technology in order to produce one-inch combustion chamber /nozzle assembly (thruster) that can withstand complex configurations. Five cycles were run on the thruster with hydrogen/oxygen propellant. The last cycle was a five-minute one at 1320°C.
Health profession.
There are many orthopedic applications for silicon nitride. It can be substituted for PEEK and titanium in spinal fusion devices. The materials’ strength, durability, reliability, and resistance are significantly higher than those of PEEK (polyether ketone) and titanium. Some components of the material are antibacterial, antifungal and antiviral.
Tools for metal cutting and welding.
It is used in cutting tools because of its hardness, thermal stability, wear resistance and toughness. It is particularly recommended to high-speed cast iron machining. Sintered silicon Nitride can be used to machine cast iron, nickel-based alloys, hard steel, and other metals 25 times quicker than traditional materials, such as tungsten caride. Manufacturing output can be greatly affected by the quality of cutting tools. The face milling process of gray cast steel with silicon nitride blades, in comparison to traditional tungsten-carbide tools, doubles cutting speed and increases tool life by up to six blades per piece. This reduces the overall cost of the blades by 50%.
Electronic Industry.
Silicon nitride has been used to electrically isolate structures and as an adhesive in integrated circuit manufacturing. Silicon nitride is an excellent passivation material for microchips. It has a much better diffusion barrier than silicon dioxide to both water molecules and sodiumions, which are the main causes of corrosion and instability within microelectronics. It can be used in an analog chip capacitor as a dielectric to separate polysilicon layer.
