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 composed of single crystals embedded in the amorphous, partially crystalline glass phase matrix. These properties are not dependent only on the inherent silicon nitride properties, but also the size, morphology, and volume fraction of the glass phase at silicon nitride-grain boundaries. Si3N4 can be used for both traditional and more innovative applications. Si3N4 has many advantages, including its light weight, high wear resistance, excellent bending strength and durability. This makes Si3N4 an attractive alternative to conventional materials like stainless steel and tungsten carbide.
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 that reduce engine emissions. 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 the tracks. This is a better alternative to traditional metal bearings. They can lower friction by as much as 80% and extend their service lives by up 3-10 times. Silicium nitride is 79% lighter that tungsten caride balls. High-end bearings made of silicon nitride can be used for 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 few ceramic materials that is capable of enduring 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-diameter combustion chamber /nozzle (thruster), assemblies. Five cycles were run on the thruster with hydrogen/oxygen propellant. The last cycle was a five-minute one to 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, and hard steel at 25 times the speed of conventional 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 is a great way to increase production output.
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.
