Abstract
Catalyst extraction from polycrystalline diamond table may be achieved by treating with a halogen (in the gas phase or dissolved in a nonpolar organic solvent) to convert the catalyzing material to a salt. Then, polar organic solvents may optionally be used to leach the salt from the polycrystalline diamond table. The polycrystalline diamond (with the salt of the catalyzing material present or at least partially leached therefrom) may be brazed to a hard composite substrate to produce a cutter suitable for use in a matrix drill bit.
