Introduce

Silicon nitride (Si3N4) ceramic materials are widely used in manufacturing, aerospace, chemical, armor, and other fields because of their high strength, wear resistance, corrosion resistance, and other properties. Using the appropriate sintering additives can effectively improve the thermal conductivity, the fracture toughness and promote the improvement of material properties.

With these performances, silicon nitride is a good material for riser tubes.
