Description
Elektrolytisches Zinnbad zur Darstellung schwammfreier Zinnkristalle. Bei der galvanischen Entzi,nnuin,g zinnhaltiger Abfälle sowie bei Raffinatnonsprozessen wird das Zinn größtenteils als Sch@wamm@ gewonnen, der, aus höchst fein verteiltem Zinn bestehend, große Neigung zur Oxydation hat, beim :Einschmelizen ,durch Verbrennung über 5o Prozent oxydischen Rückstand iergiibt, der einer erneuten Aufarbeitung .bedarf. Lötmittel in Salben- und: Stangenform, zu deren Darstefung ,man. @meist gal"vanisah nfiedergesehlagernes Zinn verwendet, verbrennen zum Teil bei der Anwe@ndumg, wodurch die Wirkung beeinträchtigt wird'. Dieser Übelstand wird- durch ,das ,nachstehend beschräebene Verfa,hren vermieden, dienn es gelingt damit, große Kristalle zu erzeugen, die -sich fasst verlustfrei schmelzen lassen, die man aber, wenn sie zu Lötmitteln verwendet werden sollen, leicht zerkleinern kann. Der Elektrolyt ist ferner vorteilhaft zur Trennung des Quecksilbers von, Zinn (Spii-egelamaligam) zu: gebrauahen. Es ,biliden sich die ZnnnkrIstalle, während metallisches Ouecksiilber zurückbleibt. Zur Raenation jes Zinns verwendet, findet man beim E lektrolysieren ,das Blei ,des stark bleihaltigen Materials nur in !Spuren ir_ den Kristallen vor. Es hat sich gezeigt, daß diese schwammfrefen, großen. Zinnkristalle entflohen, wenn der Elektrolyt aus einer ziemlich konzentrierten 7inrnsavzlösuing besteht, welchem man: Schwefelsäure oder schwefelsaure Sa ze (sauer oder neutral) zusetzt, und zwar erwies sich amvorteiilhaftesten I. eine wäßrige Lösung, die im i- ooo Teilen 1 25 gkrist. Zi@nnchlorür und 25 g engl.Schrwefelsäure oder II. .eine wäßnige Zin:rnsalizlösung, die in i ooo Teilen Zoo g krist. Zinnchlorür und' 65 g Alu ,nvi-niumsu @fat oder ein anderes schwefelsaures Salz enthfelt.Electrolytic tin bath for the representation of sponge-free tin crystals. In the galvanic ignition of waste containing tin, as well as in raffinate processes, the tin is obtained for the most part as Sch @ wamm @, which, consisting of extremely finely divided tin, has a great tendency to oxidize, when: melting down, by incineration over 50 percent oxidic residue iergiibt, which needs a renewed work-up. Solder in the form of an ointment and: rod, for their presentation, man. @ mostly gal "vanisah nfiedergesehlstornes tin used, burns in part during use, whereby the effect is impaired. which can be melted without loss, but which can easily be crushed if they are to be used for soldering agents. The electrolyte is also advantageous for separating the mercury from the tin (Spii-egelamaligam) to: used. They form Tin crystals, while metallic silver remains. Used to refine this tin, one finds only traces of lead in the crystals during electrolysis The electrolyte consists of a fairly concentrated solution to which: sulfuric acid or sulfuric acid salts (acidic or neutral) are added, and Although I. proved to be the most advantageous an aqueous solution containing in 100 parts 1 25 g; Zinc chloride and 25 g of English sulfuric acid or II. An aqueous solution of tin: saline which, in 10000 parts, is crystalline. Tin chloride and 65 g aluminum, nvi-niumsu @fat or another sulfuric acid salt.
