Abstract
Methods of forming larger sintered compacts of PCD and other sintered ultrahard materials are disclosed. Improved solvent metal compositions and layering of the un-sintered construct allow for sintering of thicker and larger high quality sintered compacts. Jewelry may also be made from sintered ultrahard materials including diamond, carbides, and boron nitrides. Increased biocompatibility is achieved through use of a sintering metal containing tin. Methods of sintering perform shapes are provided.
