REACTION CELL OF A MULTI-PUNCH HIGH PRESSURE AND TEMPERATURE APPARATUS FOR PROCESSING DIAMOND Russian patent published in 2019 - IPC B01J3/06 C01B32/28 

FIELD: technological processes.

SUBSTANCE: invention relates to diamond processing on multi-punch apparatus of high pressure and temperature. Reaction cell of high pressure and temperature multi-punch apparatus comprises coaxially arranged cylindrical heating element 1 with end double current-conducting covers 2 and current lead rods 4, locking cell of tablet 5, and located in cell cavity substrate 6 with pressed diamond, material of which contains, wt%: NaCl = 40–60, CsCl = 40–60, diamond is made in the form of plate with ratio of thickness to length of sides of square plate from 0.1 to 0.5, wherein diameter of substrate is 1.5 times greater than length of side of diamond plate.

EFFECT: preventing cracking of diamond plates during annealing at temperatures higher than 2,500 °C and pressure of order of 7 GPa, high transparency of the medium for the beam of synchrotron radiation when it passes through the substrate, providing loss of synchrotron radiation energy of less than 50 % at 30 keV.
