Abstract

Polycrystalline diamond constructions 10 are disclosed which comprise diamond grains exhibiting inter-granular bonding and defining a plurality of interstitial regions, and a non-diamond phase at least partially filling a plurality of the interstitial regions to form non-diamond pools. The percentage of non-diamond phase in the total area of a cross-section of the body of polycrystalline diamond material is between 0 to 5 %, and the average non-diamond phase Euler number is less than 4000 as determined from an analysed image of a cross-section through the body of polycrystalline material when analysed using an image analysis technique, or is between 5 to 10 %, and the average non-diamond phase Euler number is greater than 1600 or less than 1200, or is between 10 to 15 %, and the average non-diamond phase Euler number is less than 2000, or is between 15 to 30%, and the average non-diamond phase Euler number is less than 2000.
