Abstract
A method for making a carbonate polycrystalline diamond body includes combining a first quantity of diamond with a first quantity of magnesium carbonate to form a first layer for forming a working surface, and combining a second quantity of magnesium carbonate to form a second layer adjacent to the first layer, forming an assembly. The method includes placing a quantity of silicon or aluminum in or adjacent to at least a portion of the assembly and sintering the assembly including the silicon or aluminum at high pressure and high temperature, causing the silicon or aluminum to infiltrate at least one layer of the assembly.
