Specifications of Customized Si3N4 3mm 5mm 8mm Silicon Nitride Ceramic Balls Silicon Nitride Ball

Customized Si3N4 silicon nitride ceramic balls are available in diameters of 3mm, 5mm, and 8mm. These precision-engineered components are designed for high-performance applications requiring durability, thermal stability, and resistance to wear. The material composition is silicon nitride (Si3N4), a advanced ceramic known for its exceptional mechanical properties. Key specifications include a density of 3.2-3.3 g/cm³, a Vickers hardness of 1500-1600 HV, and a flexural strength of 600-800 MPa. The balls maintain structural integrity in temperatures up to 1200°C in oxidizing environments and 1400°C in non-oxidizing conditions.

Surface roughness is controlled to a level below 0.025 μm Ra, ensuring smooth operation in precision machinery. The spherical form deviation is kept within 0.1 μm to guarantee uniform load distribution. These balls are produced using high-purity silicon nitride powder, sintered through gas pressure or hot isostatic pressing (HIP) methods. This process eliminates internal defects, enhancing reliability under extreme stress.

Electrical insulation properties make them suitable for applications requiring non-conductive components. Corrosion resistance allows use in aggressive chemical environments. The low thermal expansion coefficient minimizes dimensional changes under temperature fluctuations. Silicon nitride balls outperform steel or alumina alternatives in high-speed, high-load scenarios due to lower density and higher fracture toughness.

Common applications include bearings for aerospace, automotive, and industrial equipment, valves and pumps in chemical processing, and components in medical devices. Customization options include non-standard diameters, surface treatments, and tolerance adjustments to meet specific operational demands. Each batch undergoes rigorous quality checks for dimensional accuracy, surface finish, and mechanical performance.

Packaging is tailored to prevent damage during shipping, with options for vacuum-sealed containers or anti-static foam. Lead times vary based on order volume and customization requirements. Technical support is available for material selection, design optimization, and failure analysis.

5 FAQs of Customized Si3N4 3mm 5mm 8mm Silicon Nitride Ceramic Balls Silicon Nitride Ball

What are silicon nitride ceramic balls? Silicon nitride ceramic balls are high-performance industrial components made from silicon nitride (Si3N4). This material combines ceramic properties with exceptional strength. The balls are available in diameters like 3mm, 5mm, and 8mm. They are used in applications requiring durability under extreme conditions. Custom sizes can be produced based on specific needs.

What industries use these ceramic balls? These balls are common in automotive, aerospace, and machinery sectors. They function well in bearings, pumps, and precision tools. Their resistance to heat and wear makes them ideal for high-stress environments. Electric vehicle motors and wind turbines often rely on silicon nitride balls. Their lightweight nature improves energy efficiency in rotating systems.

Why choose silicon nitride over steel or other ceramics? Silicon nitride offers higher hardness than steel. It resists corrosion better than metals. Compared to alumina or zirconia ceramics, it handles thermal shock more effectively. The material’s low density reduces friction in moving parts. This extends component lifespan in demanding operations.

Can these balls be customized beyond standard sizes? Yes. Custom diameters, surface finishes, and tolerance levels are possible. Production adjusts to meet specifications like 3mm, 5mm, or 8mm. Tighter tolerances ensure compatibility with specialized machinery. Surface treatments enhance performance in specific applications. Bulk orders or unique designs are feasible with proper technical details.

How should silicon nitride balls be maintained? Avoid dropping or striking them against hard surfaces. Clean them regularly with non-abrasive solvents to remove debris. Store them in dry environments to prevent moisture absorption. Inspect for cracks or chips before installation. Proper handling ensures they perform reliably over time.
