Temperature- and Pressure-Reducing Regimes in the Growth Cell of HPHT Diamonds, Optimal for Preserving Crystal Integrity after Growth Completion

نویسندگان

چکیده

With its exceptional strength characteristics, diamond has some mechanical drawbacks, significant brittleness being among them. In particular, HPHT-grown diamonds crack when the extreme parameters inherent to growth process gradually decrease. The cracking is caused by excessive stress due poor plastic properties of catalytic medium at certain stages reducing pressure and temperature. An insulating container with cell heating circuit fragment inside can also make a contribution probability cracking. This paper considers possibility minimizing in and, consequently, crystal choosing optimal trajectory for decrease temperature from conditions normal conditions.
