Patent number: 7553344Abstract: A new industrial thermally stable polycrystalline diamond (TSP) is disclosed and described as a replacement of natural as well as synthetic diamond grit in concrete cutting, grinding, polishing, and surface-set grinding or core bit drilling applications. Conventional diamond is too strong and brittle for self-sharpening and polishing and has a lower thermal stability inferior to the industrial standard for high temperature tool segment bonding. TSP grits can be tailor-made having unique properties as well as an engineered shape of grits over naturally or synthetically produced diamond grits. The TSP grits have a high thermal stability of up to 1200° C. and are self-sharpening. Further, economical production of coarse TSP grit size up to 1-2 mm from 50/60 mesh size in almost any preferred shape such as blocky, round, hexagonal, thin elongated, spherical, needle like, and any desirable tailor-made shaped etc can be realized.Type: GrantFiled: June 7, 2005Date of Patent: June 30, 2009Assignee: ADICO, Asia Polydiamond Company, Ltd.Inventor: Hyun Sam Cho
