Verfahren zur Herstellung von Silizium unter gleichzeitiger Vorbereitung des in dem
Rohmaterial enthaltenen Aluminiums zu seiner Gewinnung.
Vorliegende Erfindung hotrifft ein Vorfahren zur Herstellung von Silizium unter gleichzeitiger Vorbereitung des in dem Rohmaterial enthaltenen Aluminiums zu seiner Gewinnung.
EMI1.1
eine genügend hohe Temperatur erhalten worden kann, mit einem Reduktionsmittel erhitzt. in Mengenverhältnissen, welche derart bemessen sind, dass die Kieselsäure nebst gewissen
EMI1.2
reduziert bleibt. Als Endprodukt wird man nach dem Schmelzen Silizium nebst den Metallen der betreffenden basischen Verbindungen sowie eine Schlacke erhalten, die hauptsächlich

des Prozesses abgestochen werden und dadurch kann man eventuell mehr oder weniger ausgeschiedene Produkte, z. n. Ferrosilizium gesondert von dom reinen Silizium erhalten.
Als Reduktionsmittel wird vorzugsweise metallisches Aluminium verwendet, das während des Schmelzprozesses Sauerstoff von der Kieselsäure und von den reduzierbaren basischen Verbindungen aufnimmt und Aluminiumoxyd bildet, welches mit dem Aluminiumoxyd des Silikates und den gewöhnlich kleinen Mengen unreduzierbarer basischer Verbindungen, wie von Kalk, Magnesia, Alkali die Schlacke bildet. Die derart erhaltene Schlacke kann dann zur Darstellung von Aluminium nach bekannten Verfahren verwendet werden.
Man wird dann das hinzugefügte Aluminium wiedergewinnen und ausserdem das in dem verwendeten Silikate enthaltene Aluminium :
Während des Schmelzprozesses werden die Reaktionen gemäss folgender Gleichungen vor steh gehen :

Process for the production of silicon with simultaneous preparation of the
Raw material contained aluminum for its extraction.
The present invention relates to a method for producing silicon while preparing the aluminum contained in the raw material for its recovery.
EMI1.1
a sufficiently high temperature can be obtained, heated with a reducing agent. in proportions which are such that the silica and certain
EMI1.2
remains reduced. The end product obtained after melting is silicon along with the metals of the basic compounds in question and a slag, which is mainly
EMI1.3
of the process are tapped and thereby you can possibly more or less excreted products, z. n. Ferrosilicon obtained separately from dom pure silicon.
The reducing agent used is preferably metallic aluminum, which during the melting process absorbs oxygen from the silicic acid and the reducible basic compounds and forms aluminum oxide, which, with the aluminum oxide of the silicate and the usually small amounts of irreducible basic compounds, such as lime, magnesia, alkali Forms slag. The slag thus obtained can then be used to prepare aluminum by known methods.
The aluminum added will then be recovered and the aluminum contained in the silicate used:
During the melting process, the reactions will proceed according to the following equations:
EMI1.4
EMI1.5
EMI1.6
EMI1.7
<Desc / Clms Page number 2>
Alumina with the above-mentioned composition 28.3 + 0.3 = 28.6 parts by weight of aluminum are required in order to reduce the amount of silica and iron oxide contained in the alumina.
When using ordinary Norwegian clay of the following composition:
EMI2.1
EMI2.2
Require parts by weight of pure aluminum.
