Abstract

A superhard polycrystalline construction comprises a body of polycrystalline superhard material formed of a mass of superhard grains exhibiting inter- granular bonding and defining a plurality of interstitial regions therebetween, the superhard grains having an associated mean free path, and a non- superhard phase at least partially filling a plurality of the interstitial regions and having an associated mean free path. The median of the mean free path associated with the non-superhard phase divided by (Q3-Q1) for the non-superhard phase is greater than or equal to 0.83, where Q1 is the first quartile and Q3 is the third quartile and the median of the mean free path associated with the superhard grains divided by (Q3-Q1) for the superhard grains is less than 0.47.
