摘要： Embodiments relate to methods of fabricating PCD materials by subjecting a mixture that exhibits a broad diamond particle size distribution to a HPHT process, PCD materials so-formed, and PDCs including a polycrystalline diamond table comprising such PCD materials. In an embodiment, a method includes subjecting a mixture to heat and pressure sufficient to form a PCD material. The mixture comprises a plurality of diamond particles exhibiting a diamond particle size distribution characterized, in part, by a parameter θ that is less than about 1.0, where θ = x 6 · σ , x is the average particle size of the diamond particle size distribution, and σ is the standard deviation of the diamond particle size distribution. In an embodiment, the diamond particle size distribution can be generally modeled by the following equation: CPFT 100 = D n - D S n D L n - D S n , wherein CPFT is the cumulative percent finer than, D is diamond grain size, DL is the largest-sized diamond grain, DS is the smallest-sized diamond grain, and n is a distribution modulus.
