Advanced Abrasives offers a premium line of super abrasive products customized for high pressure/high temperature sintering applications for PCD and PcBN.
During high pressure sintering a percentage of material fractures and reveals new surfaces that were previously intrinsic to the crystal. If the material has high internal impurities they will reveal themselves at the surface once the crystal fractures. These impurities may result in inefficient sintering/bonding due to contaminant migration into the catalytic/solvent system and/or between the diamond-to-diamond interface. A low level of intrinsic impurities is essential in optimizing the sintering process. Advanced Abrasives selects premium feedstock crystal with the lowest level of intrinsic impurities currently available.
