CHARGE FOR MANUFACTURE OF THE CONTAINER OF THE HIGH-PRESSURE APPARATUS Russian patent published in 2006 - IPC C04B35/03 C04B35/00 

FIELD: high-pressure engineering; production of containers of the high-pressure apparatuses.

SUBSTANCE: the invention is pertaining to the field of high-pressure engineering, in particular, to the composition of the charge for manufacture of the containers of the high-pressure apparatuses (HPA), which are used predominantly for synthesis of the ultra-hard materials (UHM), such as diamonds and the cubic boron nitride, and for sintering of polycrystals on their base. The technical result of the invention is reduction of the number of depressurizations at the synthesis process of the ultra-hard materials, due to what the service life of the high-pressure apparatuses is increased as well as the yield of the ultra-hard materials, which is produced as the result of the synthesis, and the improved environment. The charge for manufacture of the containers of the high-pressure apparatuses contains the filler and the plasticizer. In the capacity of the plasticizer the charge contains at least hexagonal boron nitride in amount of 1.5 - 18.0 % of the charge mass. In the capacity of the filler use limestone, dolomite or pyrophyllite.

EFFECT: the invention ensures reduction of the number of depressurizations at the synthesis process of the ultra-hard materials and the improved environment.
