High Surface Polished Ra0.1 Si3N4 Ceramic with high dimensional accuracy not adhere to the metal and no chemical reaction

Product Description:

Silicon Nitride Ceramics, often referred to as SI3N4 ceramic balls, are advanced engineering materials known for their exceptional mechanical and thermal properties. These ceramics have gained widespread recognition in various industrial applications due to their superior performance characteristics. One of the most notable attributes of SI3N4 ceramic balls is their impressive fracture toughness, which ranges between 5.5 and 6.5 MPa·m ^1/2 . This high fracture toughness ensures that the material can withstand significant stress and resist crack propagation, making it ideal for demanding environments where durability and reliability are critical.

The density of Silicon Nitride Ceramics is approximately 3.2 g/cm ³ , which is relatively low compared to other ceramic materials. This low density contributes to the lightweight nature of SI3N4 ceramic balls, allowing for applications where weight reduction is essential without compromising strength. The combination of low density and high strength makes these ceramics particularly valuable in aerospace, automotive, and high-speed machinery industries.

Another key characteristic of SI3N4 ceramic balls is their excellent thermal conductivity, ranging between 20 and 25 W/m·K. This property enables efficient heat dissipation, which is crucial in high-temperature applications or components exposed to rapid temperature changes. The ability to maintain thermal stability while conducting heat effectively reduces the risk of thermal shock and enhances the overall lifespan of parts made from Silicon Nitride Ceramics.

Hardness is a critical factor when evaluating the wear resistance of materials. SI3N4 ceramic balls exhibit a high hardness level, typically between 1500 and 1650 HV (Vickers Hardness). This substantial hardness ensures that these ceramic balls can endure abrasive conditions and prolonged mechanical contact without significant wear, maintaining their performance and dimensional stability over time. The hardness also contributes to the material’s resistance to deformation under load, further enhancing its suitability for high-stress applications.

Compressive strength is another vital mechanical property of Silicon Nitride Ceramics, with values reaching up to 3800 MPa. This exceptional compressive strength means that SI3N4 ceramic balls can sustain extreme loads without failure, making them perfect candidates for use in bearings, seals, and other components subject to high compressive forces. The combination of high compressive strength and fracture toughness ensures that the material performs reliably under both static and dynamic loading conditions.

SI3N4 ceramic balls are widely utilized in precision machinery, bearing components, and high-performance engineering systems due to their balance of strength, toughness, and thermal properties. Their resistance to corrosion and chemical stability further extend their applicability in harsh environments, including chemical processing and semiconductor manufacturing. Moreover, the material’s ability to operate effectively at elevated temperatures without degradation makes it an excellent choice for applications in engines and turbines.

In summary, Silicon Nitride Ceramics offer a remarkable set of properties that make SI3N4 ceramic balls highly desirable in a variety of advanced technological fields. Their fracture toughness of 5.5-6.5 MPa·m ^1/2 , density of 3.2 g/cm ³ , thermal conductivity of 20-25 W/m·K, hardness between 1500-1650 HV, and compressive strength of 3800 MPa collectively contribute to their outstanding performance. Whether in demanding mechanical systems or high-temperature applications, SI3N4 ceramic balls provide an excellent combination of durability, strength, and thermal management, making them indispensable in modern engineering solutions.
