Emerging applications of silicon nitride include micro-electromechanical system (MEMS) devices, LED lighting, and solar cells. Advancements in material synthesis technologies are also helping reduce costs and improve material properties. However, the availability of substitute materials could limit the market growth to some extent over the coming years.

Superior mechanical properties

Silicon nitride ceramics possess outstanding mechanical properties such as high strength, toughness, and hardness. It exhibits high strength even at elevated temperatures, making it an excellent material for applications requiring durability under harsh or extreme conditions. Silicon nitride has a flexural strength of over 700 MPa and a Vickers hardness of over 1500 kg/mm2. The high strength and hardness of silicon nitride enables it to withstand high impact and compressive loads. It also offers high stiffness, translating to dimensional stability and resistance to thermal shock. Silicon nitride's strength remains unaffected even after exposures to temperatures as high as 1400°C. Owing to its impressive mechanical resilience, silicon nitride parts can endure intensive use in demanding industrial applications. The material finds extensive use as bearing balls and rolls, seal rings, turbine engine components, cutting tools, and wear parts in various industries such as automotive, aerospace, oil and gas where components are subjected to heavy duty cycles and high mechanical stresses over long periods of time under different operating conditions. The excellent retention of mechanical properties at high temperatures has prompted increased development and utilization of silicon nitride ceramics to replace metallic alloys in critical high-performance applications.

The automotive industry is undergoing rapid transformation with a strong focus on lightweight vehicle design, improved performance and fuel efficiency. This presents considerable opportunities for silicon nitride which offers attractive properties for automotive applications. Silicon nitride ceramic components help reduce weight and boost performance of vehicles. Its high strength-to-density ratio enables significant weight savings compared to conventional materials such as aluminum alloys. Lighter vehicles translate to better mileage and lower emissions. Silicon nitride is an attractive material for engine components operating at high temperatures such as turbocharger rotors, exhaust manifolds, and thermal sleeves, because of its retained strength and wear resistance even at elevated temperatures exceeding 1000°C. It also finds growing usage in brake components due to the excellent wear resistance and performance consistency even under harsh braking conditions. The non-metallic and corrosion resistant nature make silicon nitride suitable for under-hood applications as well. With automotive Original Equipment Manufacturers under constant pressure to comply with stringent fuel-efficiency and emission standards, advanced ceramics such as silicon nitride are expected to gain wider acceptance in automotive systems over the coming years. This will augur well for the silicon nitride market.
