Silicon Nitride Ceramics, also known as SI3N4 ceramic balls, are a type of advanced ceramic material with extremely high strength and excellent thermal stability. They are manufactured using a sintering process, making them highly resistant to compression, bending and other external forces. With a compressive strength of 3800 MPa, bending strength of 750 MPa, Poisson's ratio of 0.25-0.3, insulation resistance of 1012-1014 Ω.cm, and thermal conductivity of 20 W/m.K, Silicon Nitride Ceramics are widely used in a variety of industries such as aerospace, automotive, medical, and electrical engineering. They are also used in precision bearings, valves, pumps, and other mechanical components, due to their superior strength, corrosion resistance, and wear resistance.
