FIELD: powder metallurgy, namely processes for removing plasticizing agent.
SUBSTANCE: method for capillary type removing of binder comprises steps of preparing mixture, mixing it with plasticizing agent, pressing prepared mixture and heating it for removing plasticizing agent. Before pressing, highly volatile liquid is added to mixture in quantity consisting 0.4 - 0.6 of pore volume of pressed material for dissolving plasticizing agent. Heating is realized before sintering until volatile liquid separation is ended and plasticizing agent appears on surface of pressed material.
EFFECT: shortened time period for removing plasticizing agent, improved quality of articles.
