Claim 0:
1. A method of fabricating a polycrystalline diamond element, the method comprising:
positioning a first volume of diamond particles adjacent to a substrate, the first volume of diamond particles including a material comprising a group 13 element;
positioning a second volume of diamond particles adjacent to the first volume of diamond particles such that the first volume of diamond particles is disposed between the second volume of diamond particles and the substrate, the second volume of diamond particles having a lower concentration of the material comprising the group 13 element than the first volume of diamond particles;
enclosing the substrate, the first volume of diamond particles, and the second volume of diamond particles in a pressure transmitting medium to form a cell assembly; and
subjecting the cell assembly to a high-pressure/high-temperature process to form a polycrystalline diamond table coupled to the substrate.
