Specifications of Hard High Polished Si3N4 Silicon Nitride Ceramic Long bar Rod

The Hard High Polished Si3N4 Silicon Nitride Ceramic Long Bar Rod is designed for demanding industrial applications. It is made from premium silicon nitride (Si3N4) ceramic, a material known for exceptional strength and durability. The composition includes over 95% silicon nitride, ensuring high thermal stability and resistance to wear. This rod is ideal for environments requiring reliability under extreme conditions.

The standard diameter ranges from 3mm to 25mm, with lengths up to 500mm. Custom sizes are available for specific needs. The surface finish is precision-polished to a mirror-like quality, reducing friction and improving performance in high-contact applications. Tight dimensional tolerances are maintained, typically within ±0.05mm, to ensure consistency.

This ceramic rod offers a hardness of HRA 92, surpassing many metals and alloys. It has a flexural strength of 800-1000 MPa, making it suitable for heavy-load scenarios. The material resists deformation even under intense pressure. Its fracture toughness reaches 6-7 MPa·m¹/², minimizing crack propagation risks.

Thermal properties are a key advantage. The rod withstands temperatures up to 1200°C in air and 1400°C in inert atmospheres. It resists thermal shock, handling rapid temperature changes without damage. Thermal conductivity is low, around 15-25 W/m·K, ensuring energy efficiency in high-heat settings.

Chemical resistance is excellent. The rod does not react with acids, alkalis, or corrosive gases. It performs reliably in harsh chemical environments. Electrical insulation properties are strong, with a volume resistivity exceeding 10¹⁴ Ω·cm, making it safe for electrical applications.

Applications include aerospace components, automotive engine parts, industrial bearings, and cutting tools. It is used in semiconductor manufacturing for wafer handling and in metallurgy for high-temperature fixtures. Medical equipment manufacturers use it for its biocompatibility and sterilization resistance.

Quality control follows ISO 9001 standards. Each batch undergoes rigorous testing for density, porosity, and mechanical performance. Density is maintained at 3.2-3.3 g/cm³, with near-zero porosity to prevent structural weaknesses.

Packaging uses anti-static materials to prevent contamination. Custom packaging is available for bulk orders or fragile specifications.
