Premium Diamond Feedstock

Premium Diamond Feedstock


Advanced
Abrasives Corporation offers a premium line of superabrasive 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
