Silicon nitride is a composition of silicon and nitrogen chemical elements. It is thermodynamically stable and used in an extensive range of applications. Silicon nitride balls are made from silicon nitride powder by a series of processes, also known as silicon nitride ceramic balls. These balls are gray or black in color and are mainly used in bearings. These balls are appropriate for applications where factors for instance high loads, high speeds, and extreme temperatures are required. These are lighter than steel, non-porous, non-magnetic, and non-corrosive. These balls are non-porous, thus, they are capable of rotating faster than steel balls and are approximately frictionless. Silicon nitride balls are used for high running speed and for high temperature applications in machine tool spindles, motor racing, high speed air turbine bearing, dental drills, aerospace, and in biotechnology industry. Additionally, silicon nitride (Si3N4) ceramic has become a standard ceramic ball material for hybrid ball bearings, which is very hard, over 2000 Knop, and very wear resistant. Moreover, weight of these balls in only 40% of steel at 3.2 grams per cm, and it has excellent facture strength even at elevated temperature.
