  With the rapid development of modern mechanical engineering technology, the requirements for material properties are increasingly stringent, especially under extreme conditions such as high temperature, high speed, strong corrosion, etc., traditional metal materials and polymer materials have been difficult to meet the needs. Silicon nitride (Si ₄) As an advanced ceramic material with excellent overall properties, the silicon nitride balls made of it show their unique characteristics and wide application prospects in the field of mechanical engineering. In this paper, the properties and characteristics of silicon nitride balls are reviewed, their specific applications in mechanical engineering are discussed, and their future development trends are prospected.   Silicon nitride ceramics are known as "the pearl in the crown of advanced ceramics" for their high strength, high hardness, good thermal stability, corrosion resistance, oxidation resistance and self-lubrication. As ...
