Silicon nitride
This all-rounder among the high-performance ceramics offers an entire range of advantages for the most diverse applications. This low-density material is very low in weight, making it particularly interesting for devices that perform rotating or pivoting movements.
Silicon nitride is very hard and has a high chemical resistance, similar to aluminium oxide, but is closer to zirconium oxide in terms of impact strength. It can, therefore, be found throughout the field of mechanical and plant engineering in applications where many issues occur at the same time.
However, its greatest advantage is in its high temperature and thermal-shock resistance, which places this material, e.g., in induction plants. Beyond this, silicon nitride preserves its full strength in a temperature range up to nearly 1000 °C. It shows barely any expansion at all.
