Silicon Nitride (Si3N4) combines the best electrical, thermal, and mechanical properties of any ceramic material. It is the best solution for applications where other ceramic materials prove to be too weak to handle mechanical stress or thermal shocks.With its excellent combination of properties, Silicon Nitride is highly sought after in industries requiring high-performance materials that can withstand extreme conditions. Its superior strength, toughness, and thermal shock resistance make it an ideal choice for applications such as cutting tools, bearings, and turbine engine components. Additionally, its electrical insulating properties make it suitable for use in high-temperature and high-voltage applications. When it comes to demanding environments, Silicon Nitride stands out as a reliable and durable material that exceeds
High Bending Strength about Twice as high as Alumina and Aluminum Nitride (AlN) Substrate
