Silicon Nitride Balls
170 ProductsSilicon Nitride Balls are ceramic balls made from silicon nitride (Si3N4). These balls are known for their outstanding mechanical properties. They are essential in many fields, such as aerospace, defense, renewable energy, and advanced manufacturing.
Features of Silicon Nitride Balls
- High Corrosion Resistance: Silicon Nitride Si3N4 Ceramic Balls resist corrosion from a wide range of chemicals, making them ideal for applications in harsh environments.
- Lightweight Design: Lighter by 60% than steel, Silicon Nitride balls cut centrifugal force on bearings. This reduction in force minimizes skidding and wear during high-speed operations and acceleration.
- Durable: With a density of 3.2 g/cc, flexural strength of 1.0 GPa, fracture toughness of 6 MPa/M2, and hardness of 75-80 HRC, Silicon Nitride Balls are harder than steel, making them ideal for tough uses.
- High-Temperature Stability: They retain their strength and hardness even at temperatures up to 1800°F, making them suitable for applications where high speeds and extreme temperatures are factors.
