APPARAT FOR FREMSTILLING AV METALLER MED HOEYT SMELTEPUNKT OG HOEY SEIGHET

摘要

In an apparatus for preparation of high-melting-point high-toughness metals by reduction of chlorides thereof with an active metal which comprises a heatable and tightly closable reaction chamber, an evacuable and coolable condensation chamber for separating the unreacted active metal and the formed chloride of the active metal from the formed object metal and an intermediate connecting section for communicating and cutting off the two chambers, the improved apparatus which is characterized in that it comprises a seal pot closing means having a funnel and a pot which is closed by introducing a melt of a fusible and vaporizable material and solidifying it therein, is disclosed.
