  • Patent number: 9388083
    Abstract: Disclosed are a silicon carbide sintered body and a sliding component using the same, and a protective body which, even when fine cracks are generated due to thermal shock or mechanical impact over prolonged use, are capable of inhibiting development of the cracks. The silicon carbide sintered body contains silicon carbide grains as a major component and has a relative density of 95% or more. On an observation surface of the silicon carbide sintered body, coarse silicon carbide grains 1b having a surface area of 170 ?m2 or more occupy 6 area % or more and 15 area % or less. The silicon carbide sintered body has excellent mechanical properties such as strength and rigidity. Even when fine cracks are generated due to thermal shock or mechanical impact, coarse silicon carbide grains 1b are capable of inhibiting development of the cracks.

  • Patent number: 9293384
    Abstract: A silicon nitride substrate comprises a substrate comprising a silicon nitride sintered body, and a plurality of granular bodies containing silicon and integrated to a principal surface of the substrate, wherein a plurality of needle crystals or column crystals comprising mainly silicon nitride are extended from a portion of the granular bodies. A brazing material is applied to a principal surface of the substrate, and a circuit member and a heat radiation member are arranged on the applied brazing material, and bonded by heating. Because of a plurality of granular bodies integrated to the principal surface of the substrate, and a plurality of the needle crystals or the column crystals extended from a portion of the granular bodies, a high anchor effect is produced so that the circuit member and the heat radiation member are firmly bonded to the silicon nitride substrate.
