Nano Silicon Nitride (Si3N4) (CAS: 12033-89-5) is a dense, high-strength, and high-toughness ceramic material developed by scientists in the 1970s. Silicon nitride has been used in many industrial applications such as engine components, bearings, and cutting tools. Silicon nitride has better high-temperature performance than most metals, combined with high strength stability and creep and oxidation resistance. In addition, its low coefficient of thermal expansion makes it good thermal shock resistance compared to most ceramic materials.
