    摘要: A sliding member having a sliding surface comprising a silicon carbide sintered body having a primary phase comprising mainly silicon carbide, and a subphase having a different composition from the primary phase and containing at least boron, silicon and carbon. The ratio of pores having a roundness of 6 μm or less and a pore diameter of 10 to 60 μm with respect to all pores having a pore diameter of 10 μm or more in the sliding surface is 60% or more. This enables retention of good seal properties even in a long-term continuous use. The subphase in the silicon carbide sintered body is preferably granular crystal phases dotted among a plurality of the primary phases. This provides excellent lubricating liquid holding performance as well as excellent thermal conductivity and excellent thermal shock resistance properties.

    摘要: Provided is a sliding member which includes a plurality of open pores in a sliding surface, which each comprises one or more opening portions having a circularity of 0.24 or more and a circle equivalent diameter of 10 μm to 150 μm. A ratio of the number of open pores having the overlapping degree of 10% or more between the opening portions is 3% or less. Another sliding member includes a plurality of open pores in a sliding surface, which each comprises one or more opening portions having a circularity of 0.24 or more and a circle equivalent diameter of not less than 10 μm nor more than 78 μm. A coefficient of variation of the opening portions satisfies the following equation: 1.03≦√V/X≦1.51 where √V is a standard deviation of circle equivalent diameters, and X is an average value of the circle equivalent diameters. A mechanical seal ring, a mechanical seal and a faucet valve each using the sliding member are also provided.
