摘要:
A granulation method for granulating a (CuX)6Sn5 compound by passing a composition comprising a (CuX)6Sn5 compound and tin through a multi-perforated plate to granulate the (CuX)6Sn5 compound wherein X represents an element which is solved in Cu but forms a precipitate with Sn.

摘要:
A method by which the amount of nickel contained in an alloy having a composition represented by Sn—X—Ni can be regulated. The method of nickel concentration regulation comprises adding phosphorus to Sn—X—Ni in a molten state (wherein X is one or more elements selected from the group consisting of Ag, Zn, Cu, Bi, Au, Ti, Ge, Ga, Si, and Ce), holding the mixture at 250-400° C., and removing the resultant dross floating on the surface of the liquid phase and containing a P—Ni compound and a P—Sn—Ni compound. An example of X is copper, and the content thereof may be 0.3-5 wt %. The phosphorus may be added in the state of a Sn—P alloy. The upper limit of the amount of the phosphorus to be added may be about half the nickel amount in terms of atomic amount.

A soldering apparatus includes a solder wave shape forming means for melting solder and forming a solder wave shape, and a separating agent dusting means for dusting solder oxides with a separating agent which separates solder and solder oxides. The separating agent is any one selected from the group consisting of offal, cereal grain or flour, bean flour, seed grain or flour, soybean-cake flour, and peanut hull flour, or a combination thereof, as well as an agent and a method of separating solder and solder oxides.
摘要:
A process is disclosed for the suspension or flash smelting of finely-divided oxide and sulfide ores and concentrates, a process in which a suspension of a finely-divided raw material in preheated air or oxygen is fed downwards at the reaction temperature or a higher temperature in a reaction zone formed together by the suspension and the smelt underneath in order to oxidize and partially smelt the suspension raw material, whereafter the oxidized raw material is partially sulfidized and the suspension flow is made to change its direction perpendicularly to the side so that the bulk of raw material in the suspension flow impinges towards the surface of the accumulated smelt in the main smelt reaction zone under the suspension reaction zone, and the remaining suspension flow is fed to a zone which has a rising flow, where the suspension is possible after-sulfidized and cooled and the solids to be returned to the suspension reaction zone are separated from the residual suspension flow. The suspension flow portion not impinging against the smelt surface in the main smelt reaction zone is fed into a secondary reaction zone wherein it is allowed to, at least, partially dissolve in the smelt before the undissolved residual suspension is fed into the rising-flow zone so as not to affect a smelt settling zone communicating with the main and secondary smelt reaction zones and in which slag is separated from matte and metal.
摘要:
Any metal having a low α-ray emission, the metal being any one of tin, silver, copper, zinc, or indium, wherein an emission of an α-ray after heating the metal at 100° C. in an atmosphere for six hours is 0.002 cph/cm2 or less. Any metal of tin, silver, copper, zinc and indium each including lead as an impurity is dissolved to prepare a hydrosulfate aqueous solution of the metal and lead sulfate is precipitated and removed in the solution. The lead sulfate is precipitated in the hydrosulfate aqueous solution by adding a lead nitrate aqueous solution including lead having an α-ray emission of 10 cph/cm2 or less to the hydrosulfate aqueous solution, from which the lead sulfate has been removed, and, at the same time, the solution is circulated while removing the lead sulfate to electrowinning the metal using the hydrosulfate aqueous solution as an electrolytic solution.
摘要:
A deoxidation system for purifying target material for an EUV light source includes a furnace having a central region and a heater for heating the central region in a uniform manner. A vessel is inserted in the central region of the furnace, and a crucible is disposed within the vessel. A closure device covers an open end of the vessel to form a seal having vacuum and pressure capability. The system also includes a gas input tube, a gas exhaust tube, and a vacuum port. A gas supply network is coupled in flow communication with an end of the gas input tube and a gas supply network is coupled in flow communication with an end of the gas exhaust tube. A vacuum network is coupled in flow communication with one end of the vacuum port. A method and apparatus for purifying target material also are described.
