Specifications of Si3n4 Ceramic Ball 3mm 4mm 5mm 10mm Self-lubricating High Hardness High Purity Silicon Nitride Ceramic Grinding Ball

The Si3N4 ceramic ball comes in sizes of 3mm, 4mm, 5mm, and 10mm. It is made of high-purity silicon nitride for reliable performance. The material offers extreme hardness, reaching over HRA 90, making it resistant to wear. This hardness ensures long service life even under heavy stress. The ceramic ball works well in high-temperature environments, handling up to 1200°C without losing strength. It stays stable in rapid temperature changes, avoiding cracks or deformation.

The self-lubricating feature reduces friction during motion. This lowers energy loss and prevents surface damage. It is ideal for grinding applications where smooth operation matters. The balls are chemically inert, resisting acids, alkalis, and solvents. This makes them suitable for harsh chemical settings. They avoid contamination in sensitive processes like semiconductor manufacturing or medical equipment.

Precision is key. Each ball has a diameter tolerance within ±0.05mm, ensuring uniformity. The surface finish is polished to a roughness below Ra 0.05μm. This minimizes particle generation during use. The high density of 3.2-3.3 g/cm³ adds durability. These balls outperform steel or alumina options in lifespan and efficiency.

Applications include grinding mills, bearings, pumps, valves, and precision instruments. They are used in aerospace, automotive, and electronics industries. The material’s low thermal expansion coefficient prevents size changes under heat. This keeps machinery running accurately.

Packaging options include vacuum-sealed bags or custom containers. Bulk orders are available. The product meets ISO 9001 standards for quality control. Custom sizes or specifications can be requested. Technical details include a flexural strength of 600-800 MPa and fracture toughness of 6-7 MPa·m¹/². These properties ensure reliability in demanding conditions.

Applications of Si3n4 Ceramic Ball 3mm 4mm 5mm 10mm Self-lubricating High Hardness High Purity Silicon Nitride Ceramic Grinding Ball

Si3N4 ceramic balls in sizes 3mm 4mm 5mm 10mm are engineered for high-performance applications. These balls are made from silicon nitride, a material known for exceptional hardness and durability. They work well in extreme conditions like high temperatures, heavy loads, and corrosive environments. Their self-lubricating properties reduce friction and wear during operation. This makes them ideal for machinery parts that need long-lasting performance with minimal maintenance.

The high hardness of silicon nitride ceramic balls ensures resistance to deformation under pressure. They outperform steel and other ceramics in abrasive settings. This quality is critical in grinding and milling equipment where consistent precision matters. The 3mm to 10mm size range allows flexibility for use in small-scale tools and larger industrial systems.

High purity is another key feature. The material lacks contaminants that could affect sensitive processes. This makes the balls suitable for semiconductor manufacturing, medical devices, and chemical processing. In electronics, they prevent impurities during component production. In the pharmaceutical industry, their inert nature ensures no interaction with reactive substances.

Self-lubrication reduces the need for external lubricants. This cuts downtime for maintenance and lowers operational costs. Applications include bearings, pumps, and valves in automotive, aerospace, and energy sectors. The balls handle high-speed rotations without overheating or losing structural integrity.

Silicon nitride’s thermal stability allows use in environments exceeding 1000°C. It resists thermal shock, maintaining performance despite rapid temperature shifts. Corrosion resistance makes these balls reliable in acidic or alkaline settings. Industries like metal processing and marine engineering benefit from this trait.

The combination of hardness, purity, and self-lubrication positions Si3N4 ceramic balls as a versatile solution. They improve efficiency in precision equipment, reduce contamination risks, and extend service life across industries. Their adaptability to diverse operational demands makes them a practical choice for advanced engineering needs.

5 FAQs of Si3n4 Ceramic Ball 3mm 4mm 5mm 10mm Self-lubricating High Hardness High Purity Silicon Nitride Ceramic Grinding Ball

What material are these ceramic balls made of?
These ceramic balls use silicon nitride (Si3N4) as the main material. The manufacturing process ensures high purity. This material choice gives the balls their key properties like hardness and heat resistance.

Why pick silicon nitride over other materials?
Silicon nitride stands out for its high hardness and strength. It resists wear better than metals or other ceramics. It handles extreme temperatures without losing performance. The self-lubricating feature reduces friction. This makes it ideal for heavy-duty or high-speed applications.

How does the self-lubricating feature work?
The surface of silicon nitride forms a thin layer when interacting with moisture or other elements. This layer acts like a lubricant. It cuts down friction and wear during operation. No extra lubricants are needed. This keeps maintenance simple and costs low.

Where can these ceramic balls be used?
They work in many industries. Common uses include grinding media in mills, bearings in machinery, and parts in automotive or aerospace systems. They suit environments needing high precision, chemical resistance, or thermal stability.

What sizes are available? Do they last long?
Sizes include 3mm, 4mm, 5mm, and 10mm. The lifespan depends on operating conditions. Silicon nitride’s hardness and wear resistance typically ensure longer service than metal or standard ceramic balls. Proper use and regular checks help maximize durability.
