Abstract
The Belarus producer ADAMAS has realized the synthesis of large diamond sin gle crystals of up to 4 carat, having an extraordinary hardness in some par ts of the crystals. This process was carried out at high pressure acid high temperature, using the Russian BARS-technology. The special properties of this process and the design of the reaction cell are published here for the first time. Furthermore, preliminary results on the mechanical properties and the structure and distribution of defects in diamond single crystals, t hat were synthesized by this process, are given.
