| 1. A method of making shaped thermally stable polycrystalline diamond material, comprising the steps of:
a) preparing a partition member having a plurality of shaped openings corresponding to a predetermined shape;
b) placing a particulate feed charge into the shaped openings to form a charged partition, said particulate feed charge including
a substantially homogenous mixture of diamond, inorganic bonding medium, and an inorganic binder agent; and
c) subjecting the charged partition to a high temperature and a high pressure for a time sufficient to form thermally stable
polycrystalline material of the particulate feed charge, wherein said thermally stable polycrystalline material is bonded
together primarily by cementing adjacent particles via a secondary material rather than by sintering.
