Properties of Silicon Nitride Ceramics
Silicon nitride ceramics are suitable for applications ranging from fracking and pipelines to aerospace engines and high-speed industrial manufacturing equipment. These materials are man-made, and were developed for applications requiring wear part use. Key characteristics include:
- Corrosion resistance.
- Chemical resistance.
- High strength at a wide range of temperatures.
- High fracture toughness and high hardness.
- High thermal conductivity and shock resistance.
- Wear resistance.
- Low density.
- Low thermal expansion.
The material is dark gray to black in color and can be polished to a very smooth reflective surface. The performance-to-cost-benefit ratio for silicon nitride is excellent in applications where it outperforms normally-utilized ceramics materials, with a long service life and reliably low maintenance.
Advantages of Silicon Nitride Ceramics
Silicon nitride ceramics have several advantages when compared to traditional ceramics and nonmetals. Core benefits of using these materials for industrial machinery components include:
- Corrosion resistance: Much more resilient against oxidation and corrosion compared to metals and other ceramics.
- Chemical resistance: Can withstand exposure to a wide range of chemicals commonly used in oil and gas processing, engine assemblies, and industrial machinery.
- Cost-effectiveness: Can be used through repeated industrial cycles for an excellent price per use. Their durability also reduces maintenance and replacement costs.
- Good strength and toughness: Strong and resistant to fracturing and mechanical damage. They also have good resistance against shock and wear.
- Thermal conductivity: Good for high-heat environments because they conduct heat and reduce the risk of thermal energy buildup in high-performance assemblies.
