Impact of COVID-19 on Silicon Nitride Market Growth

The COVID-19 pandemic significantly impacted the silicon nitride market in 2020. The imposition of country-wide lockdowns led to disruptions in the automotive, medical and aerospace industries which are major end-users of silicon nitride. Manufacturing facilities and production plants were temporarily shut down to curb the spread of the virus. This adversely affected the demand for silicon nitride ceramics worldwide. However, with progressive lifting of restrictions and resumption of industrial activities from mid-2020, the market is recovering gradually.

Silicon nitride finds major applications as journal and thrust bearings in automotive engines. During the initial lockdown phase, automotive sales declined sharply impacting the demand for bearings. Medical devices and implants manufactured using silicon nitride also witnessed reduced demand as non-essential surgeries and procedures were postponed. Aerospace was another severely hit sector with grounding of aircrafts globally. This lowered the procurement of silicon nitride parts used in engines and airframe components.

Moving ahead, governments are now focusing on restarting manufacturing industries with safety protocols. Vaccination drives are also progressing in many countries. These positive developments are supporting the silicon nitride market to return to the growth path. Automotive, medical and aerospace sectors are likely to pick up momentum in 2021, driving the consumption of silicon nitride. Industries are also focusing more on developing innovative, high-performance materials to gain competitive advantage in the recovering economy. This presents new growth opportunities for advanced silicon nitride grades in the coming years.
