The global silicon nitride market is rapidly gaining traction owing to the excellent properties of silicon nitride at high temperature including high strength, corrosion and wear resistance, thermal shock resistance and low thermal expansion. Silicon nitride is an advanced ceramic material widely used in automotive components, cutting tools, bearings and aircraft engines due to its high strength-to-weight ratio and superior thermal shock resistance over other materials. Silicon nitride exhibits properties such as high hardness and chemical inertness and has a very high melting point of 1900°C. Key properties include high strength even at elevated temperatures (up to 1400°C), extremely low thermal expansion and good thermal shock resistance.
The Global silicon nitride market is estimated to be valued at US$ 54.92 Mn in 2024 and is expected to exhibit a CAGR of 8.1% over the forecast period 2024 to 2031.
