Abstract
Developed high-pressure chamber with a 50 % increase in reaction volume consisting of an oxide container (ZrO2 – Y2O3 ) and locking pads allow to carry out an experiment for high-pressure type “splitsphere-300” at pressures up to 7.0 GPa and temperatures up to 1600 °C and to grow diamond single crystals up to 2 carats, as well as to receive nanostructured diamond compacts and double-layer diamond carbide inserts (DCI). It was established experimentally that for uniform fi lling of all the cavities between the carbide punches and even their optimal loading a container with a porosity of 20 – 25 %.
