1. one kind by the formed anti-wear component of mainly being made up of silicon nitride of ceramic sintered bodies;

  • Said ceramic sintered bodies contain 10-3500ppm the Fe composition according to Fe element meter, greater than 1000ppm to 2000ppm according to the Ca composition of Ca element meter and the Mg composition of 1-2000ppm according to Mg element meter;

    Wherein the β

    of silicon nitride grain-compare is 95% or bigger;

    The maximum major diameter of silicon nitride grain is 40 μ

    m or lower;

    Do not detect through XRD and to be present in the Ca composition of crystal boundary in mutually, and in the hardness of said anti-wear component, fracture toughness property and the density deviation of each be in ±

    10% scope in.
