FIELD: metallurgy.
SUBSTANCE: into initial charge from tungsten of grade BA it is add 11-13 wt % of superfine tungsten powder with medium particle size 0.04-0.06 mcm. From received charge there are compressed long-measuring rectangular or square blanks with compacting force 305-350 MPa and sintering is implemented.
EFFECT: density increasing of received blanks and increasing of yield ensured by delamination removing.
