MANUFACTURING METHOD OF PRODUCTS MADE OF POWDER MATERIALS Russian patent published in 2009 - IPC B22F3/23 C22C1/04 

FIELD: metallurgy.

SUBSTANCE: from exothermal reactionary charge of initial components it is pressed charge briquette and it is located in mould in inert powder atmosphere from friable heat insulator. On surface of charge briquette it is laid gas permeable insulating barrier, in which by whole surface there are implemented openings. Pitch between centers of openings not less than three radiuses of these openings. On insulating barrier it is laid additionally layer of charge, combustion temperature of which is equal or less than combustion temperature of charge briquette. In additional layer of charge there are installed two or more initiating devices and it is initiated combustion reaction, herewith hot products of synthesis through openings in gas permeable insulating barrier it is inflamed charge briquette. After what it is implemented pressing, extraction of product from mould and cooling.

EFFECT: increasing of outlet and quality of yield, ability of increasing of overall dimensions of objective items.
