Diamond compacts, or synthetic polycrystalline diamonds, find a wide range of application as an abrasive or wear-resistant material for machining tools, wire drawing dies etc. They may find a lot more in modern industry fields as well as some futuristic fields due to their economical advantage and moderated cleavage as compared with natural or synthetic single crystals of corresponding sizes, in addition to the potential availability more in abundance than natural occurring carbonados and ballasts.
More than two decades after the first efforts to produce such diamond compacts in early sixties, diamond compact techniques are flourishing again, with a significant improvement achieved in each of sintering technique, compact structure and size, etc, putting a wide variety on market including diamond-carbide layered composite compacts.
This paper reviews literature available principally in the form of patent and tries to show which way the technique is likely to go.
