Insights, By Type: Factors Supporting the Dominance of Sintered Silicon Nitride (SSN) in the Type Segment

Sintered silicon nitride (SSN) contributes the 45.6% share among the type segments in the silicon nitride market owing to certain material properties and advantages it offers over other types. SSN involves compressing silicon nitride powder under high temperature and pressure without the addition of any sintering aids to form a dense ceramic. This produces a material that is highly dense and homogeneous in nature. The degree of purity and uniform microstructure achieved through sintering makes SSN ideal for applications requiring wear and corrosion resistance even in hostile environments. Another factor for the dominance of SSN is its excellent mechanical properties. It exhibits high hardness and flexural strength even at elevated temperatures up to 1300°C, which makes it suitable for application in systems facing thermal and mechanical stresses. The stable microstructure of SSN imparts reliability and durability not found with other types. Its resistance to thermal shocks enables use in components subjected to rapid heating and cooling cycles without failure. SSN also offers a higher density than hot pressed silicon nitride, making it a better choice for structural or load-bearing use.

 Insights, By End-use Industry: Growth of Silicon Nitride in the Medical Segment

The medical segment contributes the 41.3% share in the end-use industry distribution owing to silicon nitride's increasing role as a biocompatible material for implants and prosthetics.
