The global silicon nitride balls market is growing owing to the growing need for renewable energy production and effective grinding media for size reduction in end-use industries. Wind power has been used extensively as a clean energy source due to growing environmental consciousness and the ongoing advancement of renewable energy. The International Energy Agency reported that wind power generation climbed by a record 265 TWh (up 14%) in 2022, surpassing 2100 TWh. After solar PV, this was the renewable power technology with the second-highest growth. As significant parts, silicon nitride bearing balls are essential to wind turbines.
The primary functions of silicon nitride bearing balls in wind turbines are to support the generator rotor's rotation and maintain its balance, as well as to support the massive load of the generator rotor and enable stable operation. Additionally, silicon nitride bearing balls' hardness and high wear resistance can lessen wear and friction, increasing the bearing balls' service life and lowering maintenance and replacement expenses.
Furthermore, the investments by companies like Toshiba Materials and SKF in silicon nitride balls production are significantly driving the growth of the silicon nitride balls market by addressing rising demand across key industries, particularly automotive and renewable energy. For instance, SKF and Sinoma Nitride, an industry-leading developer and producer of silicon nitride materials and ceramic balls, have signed a Joint Venture (JV) agreement to further their collaboration in hybrid ceramic ball bearings. The collaboration is significant since ceramic bearings are a prioritized developing technology in SKF's strategy. Also, in July 2022, Toshiba Materials Co., Ltd. announced a significant investment in a new silicon nitride balls production facility in the same location as its Yokohama, Japan headquarters. The project has a budget of more than USD 38 million and began production in November 2023.
Silicon Nitride Balls Market Growth Drivers and Challenges:
Growth Drivers
- Extensive use in various end use industries: Silicon nitride balls are highly valued for their exceptional properties, including high strength, low density, resistance to wear and corrosion, and superior thermal stability. These properties make them indispensable in various high-performance applications, driving silicon nitride balls market growth. In the automotive sector, they are widely used in hybrid bearings for electric vehicles (EVs) to improve energy efficiency and reduce electrocyclic corrosion. In the aerospace and defense industry, their lightweight and durability make them ideal for precision components, while in wind energy, they enhance the reliability of turbine bearings. The material can respond to specific requirements, such as aircraft maintenance operations, as a result of the notable applications of these balls in extreme lubrication and wear conditions, such as extreme temperatures, large temperature differentials, and ultra-high vacuums.
It is anticipated that silicon nitride bearings will continue to be widely used in a variety of industrial applications because of their exceptional performance in harsh conditions. Moreover, when there are magnetic fields present, silicon nitride balls bearings work best in devices used for semiconductor fabrication. The main justification for silicon nitride in applications exposed to magnetic fields is its non-magnetic nature. In these kinds of applications, using steel balls can alter the spinning torque or disrupt the magnetic field.
According to the SEMI, original equipment manufacturers' (OEMs) worldwide sales of all semiconductor manufacturing equipment are expected to reach USD 113 billion in 2024, setting a new industry record and increasing 6.5% annually. With the help of both the front-end and back-end segments, semiconductor manufacturing equipment growth is anticipated to continue in the upcoming years, setting new records of USD 121 billion in 2025 and USD 139 billion in 2026. Therefore, the growing sales of semiconductor manufacturing equipment will drive the demand for silicon nitride balls. - Increasing use in biomedical applications: Silicon nitride balls represent an exemplary biomaterial attributable to their diverse range of material properties. Recent scientific research has facilitated innovative approaches for the application of silicon nitride in various biomedical fields. Beyond its outstanding mechanical, thermal, and chemical characteristics, silicon nitride possesses additional unique properties that enhance its utility in orthopedic applications, specifically for hip and knee replacement prosthetics as well as spinal implants. According to National Institutes of Health (NIH) estimates, the volume of total hip and knee replacements rise by 37.7% (n=130,766) and 36.6% (n=137,341), respectively, from 2018 levels by 2060. Therefore, this surge will accelerate the expansion of the silicon nitride balls market.
Notably, its partially radiolucent nature eliminates image distortions in standard radiography, thereby permitting a more accurate assessment of the implant during surgical procedures and postoperative evaluations. Having established itself as a beneficial material for spinal implants, researchers have also begun to explore the potential of silicon nitride balls for dental implants and craniomaxillofacial implants. The growing demand for metal-free dental implants has significantly contributed to the interest in silicon nitride balls within the global dental implant industry.
Challenges
- Availability of counterfeit products: Counterfeit bearings significantly contribute to frequent component failures, leading to increased expenses, heightened risks, and diminished reliability of machinery. These counterfeit products are often produced by low-wage laborers utilizing outdated equipment and substandard materials. Due to their construction, these imitation bearings closely resemble authentic ones, making it challenging for purchasers to distinguish between the two. The use of these inferior bearings results in more frequent breakdowns, thereby escalating associated maintenance and replacement costs. These additional expenses almost invariably surpass any initial savings achieved through reduced unit pricing at the time of purchase. Therefore, this factor will hinder the silicon nitride balls market from growing.
- Durability constraints caused by fatigue stress and testing limitations: Since rolling contact fatigue (RCF) causes crack growth, silicon nitride balls are susceptible to surface imperfections and may fail from fatigue spalls originating from pre-existing c-cracks or partial cone cracks. To achieve the submicron ball finishing dimension and surface characteristics that result in (unavoidable) low-velocity ball collisions and surface cracks that are triggered by the radial tensile stress field, which is maximal at the contact periphery, silicon nitride balls are manufactured using a lapping process.
C-cracks are more commonly observed in sphere-to-sphere collisions and they not only have nonplanar crack faces but also possess nonplanar crack tips, as opposed to the axisymmetric cone cracks that result from the normal collisions of spheres. With decreased CFS and increasing ball diameter, the cost of non-destructive evaluation (NDE) techniques for silicon nitride balls increases exponentially and can account for a sizeable portion of the total cost of manufacture. Inspection processes are made more difficult by the material's nonconductive nature and modest transparency.
