    Abstract: A molten metal reactor (10) quickly entrains a feed material in the molten reactant metal (16) and provides the necessary contact between the molten reactant metal and the feed material to effect the desired chemical reduction of the feed material. The reactor (10) includes a unique feed structure (24) adapted to quickly entrain the feed material into the molten reactant metal (16) and then transfer the molten reactant metal, feed material, and initial reaction products into a treatment chamber (12). A majority of the desired reactions occur in the treatment chamber (12). Reaction products and unspent reactant metal are directed from the treatment chamber (12) to an output chamber (14) where reaction products are removed from the reactor. Unspent reactant metal (16) is then transferred to a heating chamber (15) where it is reheated for recycling through the system.

    Abstract: An apparatus and method for reclaiming metal chips formed while machining metal castings to their finished shape. The apparatus includes a stationary charging tube (100) extending in a generally perpendicular direction from the charge well of a reverberatory furnace. The lower end of the charging tube is attached to a box-shaped structure (101) which has an open bottom. The sides of the structure extend into a pool of molten metal contained in the charge well. A variable rate feeder (38, 39 and 40) provides a continuous supply of metal chips to the charging tube (100) at a rate which is essentially the same as the rate at which the chips are being produced. The chips form a column (140) within the charging tube which extends through the box-shaped structure (101) and into the pool of molten metal (86). As the chips at the bottom of the column are melted, additional chips are added to the top, forcing the bottom of the column of chips into the pool of molten metal.

    Abstract: The proposed process for the continuous refining of metal involves the following steps: molten metal is fed into a reaction chamber; gaseous and solid oxidising agents are introduced; loose materials are added; the metal and slag are totally converted to a foaming emulsion; a raised pulsed pressure is created within the reaction chamber and the system is made to deviate significantly from thermodynamic equilibrium by the creation of a self-adjusting system of chemical gas-producing reactions; the emulsion is removed to a settling tank at the critical outflow-rate of the two-phase liquid; and the metal and slag are separated in the settling tank and gas is removed at a predetermined rate through the thick emulsion layer. The proposed facility for the continuous refining of metal comprises: a spherical reaction chamber (1) with a channel through which the liquid metal (5) and loose materials (4) can be introduced; a device in the form of opposing tuyeres for supplying gaseous oxygen; a cylindrical connecting channel (2); a settling tank (3) with tap holes to allow the removal of metal (20) and slag (15) and divided into two vertical channels to facilitate the separation of slag (16) and gas (17); a channel for feeding in slag-forming materials (13); and tuyeres for supplying oxygen (11 and 12).

    Abstract: α線量が0.005cph/cm 2 以下であることを特徴とする低α線ビスマス。α線量が0.2cph/cm 2 以下であるビスマスを原料とし、電気分解によりビスマス濃度を5~50g/L、pH0.0~0.4の硝酸ビスマス溶液を作製し、この溶液に吸着材を添加してポロニウムを吸着させ、これをろ過して吸着材とろ液に分離し、次にこのろ液を電解採取してビスマスを回収することを特徴とする低α線ビスマスの製造方法。最近の半導体装置は、高密度化及び高容量化されているので、半導体チップ近傍の材料からのα線の影響により、ソフトエラーが発生する危険が多くなってきている。特に、半導体装置に近接して使用される、はんだ材料に対する高純度化の要求が強く、またα線の少ない材料が求められている。本発明は、ビスマスのα線発生の現象を解明すると共に、要求される材料に適応できるビスマスのα線量を低減させた高純度ビスマス及びその製造方法を提供する。
