PERFECTIONNEMENT AUX PROCEDES D'OBTENTION DE L'ALUMINIUM.
On sait qu9il est possible d9obtenir de 1?aluminium en faisant
EMI1.1
agir un halogénure e-t de préférence du chlorure d9aluminium â l'état gazeux sur un alliage d9aluminîum,, La réaction s 9 effe otae dans le cas du chlorure d 9 altaminium à 10000-lo100 environ, sous pression réduite, suivant la formule s Aloi 3 + 2 Al.'' 3 Alcl avec formation de sous-chlorure d9alumînium.
Ce sous-chlorure est dirigé vers une zone froide où il se décom- pose suivant la réaction inverse de la précédente, en déposant de l'aluminium
EMI1.2
pur ermréréa.alat7B chlorure d 9 aluminium
Un mode opératoire courant consiste à faire barboter le gaz AlCl3 dans une masse liquide de 1-'alliage à traiter portée à la température de 1.000 à 1.100 favorable à la transformation en sous-chlorure. Mais pour que le rendement de la réaction soit bon, il est indispensable qu9il se produise un contact très intime entre le gaz et le métal.
EMI1.3
Conformément à 1, présente invention, ce contact est obtenu en'in-'" troduisant le chlorure d9aluminium¯, ou plus généralement 1?halogénure utilisé', à 19 état gazeux dans le bainrmétâlli4ue par l'intermédiaire d-'une pièce en ma- tière réfractaire pbreuse portée à une température suffisamment élevée pour que l'halogénure ne s'y condense paso
Le gaz passe à travers les pores de la pièce, se subdivise en un
EMI1.4
grand nombre de bulles qui périètrent ensuite dans le bain métallique et réagis- sent chacune avec le métal qui les entoureo
La pièce poreuse aura de préférence une forme adaptée au récipient contenant 1?alliage à traiter de telle sorte que les bulles se répartissent uniformément au sein du bain.
@
<Desc/Clms Page number 2>
Les pièces peuvent être fixées à 1?extrémité d'un tube par lequel arrive le chlorure d'aluminium gazeux et plongées dans le bain.
Une autre solution consiste à constitueren totalité ou en partie, la sole elle-même du four ou le fond du creuset, dans lequel se trouve l'allia- ge, par une matière poreuse et à introduire le chlorure d'aluminium gazeux dans une boîte étanche placée sous ce fond.
Les matières poreuses utilisées seront constituées de préférence par de l'alumine aussi pure que possible.

IMPROVEMENT IN PROCESSES FOR OBTAINING ALUMINUM.
We know that it is possible to obtain aluminum by making
EMI1.1
reacting a halide and preferably aluminum chloride in the gaseous state on an aluminum alloy. + 2 Al. '' 3 Alcl with formation of aluminum subchloride.
This subchloride is directed to a cold zone where it decomposes following the reverse reaction of the previous one, by depositing aluminum
EMI1.2
pure ermréréa.alat7B aluminum chloride 9
A common procedure consists in bubbling the AlCl3 gas in a liquid mass of the 1-alloy to be treated brought to a temperature of 1,000 to 1,100 favorable to the transformation into subchloride. But for the yield of the reaction to be good, it is essential that there be a very intimate contact between the gas and the metal.
EMI1.3
In accordance with the present invention, this contact is obtained by 'introducing the aluminum chloride, or more generally the halide used', in a gaseous state into the bainrmétalli4ue via a piece of metal. - pbrous refractory material brought to a sufficiently high temperature so that the halide does not condense therein
The gas passes through the pores of the room, subdivided into a
EMI1.4
large number of bubbles which then perish in the metal bath and each react with the metal surrounding them
The porous part will preferably have a shape adapted to the receptacle containing the alloy to be treated so that the bubbles are distributed uniformly within the bath.
@
<Desc / Clms Page number 2>
The pieces can be attached to the end of a tube through which the gaseous aluminum chloride arrives and immersed in the bath.
Another solution consists in constituting, in whole or in part, the hearth itself of the furnace or the bottom of the crucible, in which the alloy is located, with a porous material and in introducing the gaseous aluminum chloride into a box. waterproof placed under this bottom.
The porous materials used will preferably consist of alumina as pure as possible.
