Summary:A method of making a polycrystalline diamond compact includes forming multiple layers of premixed diamond particles and carbonate material, where the carbonate material includes an alkaline earth metal carbonate, and where each layer has a weight percent ratio of diamond to carbonate that is different from adjacent layers. The layers are subjected to high pressure high temperature conditions to form polycrystalline diamond.
