Description
Technical field
The invention belongs to technical field of metal material, specifically discloses a kind of sinking cathode molten-salt electrolysis and prepare among aluminium samarium
The method of alloy.
Background technique
Rare earth samarium is a kind of white metal, is mainly used in SmCo magnetic material.But currently, samarium answering in other fields
With being also continuously developed, for example the solid solubility in magnesium can improve Properties of Magnesium Alloy by solution strengthening up to 5.8%.Separately
Outside, samarium can significantly improve the synthesis service performance and corrosion resistance of aluminium alloy, be widely used in the life of metal material
It produces in preparation.
The chemical activity of rare earth element is higher, easy scaling loss and segregation is serious, if being directly added into rare earth metal in the alloy,
It will lead to the serious scaling loss of rare earth element, therefore in order to guarantee that rare earth element can play one's part to the full, under usual conditions, rare earth element
It is the addition metal in the form of rare earth intermediate alloy.The preparation method of aluminum current samarium intermediate alloy is mainly fused salt electrolysis process, is melted
Salt electrolysis method is divided into chloride system and fluoride system, wherein domestic Harbin Engineering University has studied Sm3+In chloride
(LiCl-KCl) electrochemical behavior in molten salt system.But because of SmCl3Hygroscopicity is strong, and electrolysis can generate the Cl of pollution environment2,
So chloride system is gradually fluorinated the substitution of object electrolysis system.
In fused salt electrolysis process, Sm3+Tend to obtain an electronics on cathode as Sm2+, it is difficult to it is reduced on cathode
Sm simple substance, and Sm2+Sm can be become by betatopic again in anode3+, redox-reduction circulation is formed, wastes electricity simultaneously
It accumulates in the dielectric, leading to current efficiency decline, (current efficiency refers to that the DC current of electrolytic process is actually used in oxidation, goes back
The effective rate of utilization of former something).
In order to solve the above technical problems, the applicant has applied for a kind of liquid cathode molten-salt electrolysis legal system in January, 2014
The method (application publication number CN104775137A) of standby aluminium samarium intermediate alloy, this method is with SmF3+ LiF is molten salt system,
Sm2O3For electrolyte, aluminium is liquid cathode, and graphite is anode, at 750-900 DEG C of temperature, cathode-current density 1-2A/cm2's
Under the conditions of be electrolysed.
It has been found that although above-mentioned patent solves electrolytic process wastes current problems, but generates and closed among aluminium samarium
Golden liquid can float on fused salt liquid level.When collection of products, researcher (or worker) needs to scoop out among the aluminium samarium on fused salt liquid level
Then aluminium alloy is cast, remove fused salt again after cooling and weighed and analyzed, i.e., the above method is suitable only for testing
Room lab scale, if this method is applied to industrial production, worker needs the aluminium samarium intermediate alloy liquid on a large amount of fused salt liquid level
It scoops out, not only labor intensive, and certain difficulty is brought to the design of the electrolytic cell of industrial application.
Summary of the invention
The purpose of the present invention is to provide a kind of environmental protection, and are suitable for the cathode fused salt electricity of industrial mass production application
The method that solution prepares aluminium samarium intermediate alloy.
In order to achieve the above object, base case of the invention are as follows:
A kind of method that the molten-salt electrolysis of sinking cathode prepares aluminium samarium intermediate alloy, includes the following steps,
(1) raw material is weighed respectively: SmF3、LiF、K3AlF6、Sm2O3And aluminium ingot, guarantee material quality ratio are as follows: (SmF3+
LiF):K3AlF6=20:80-10:90；
(2) by the K in step (1)3AlF6It puts into electrolytic cell, heat temperature raising, to K3AlF6SmF is added after being completely melt3
And LiF；To SmF3After being completely melt with LiF, aluminium ingot is added, Sm is added after aluminium ingot fusing2O3To fusing；
(3) molten-salt electrolysis is carried out, the cathode of molten-salt electrolysis is liquid aluminium, and anode is graphite, is closed among prepared aluminium samarium
The bottom of electrolytic cell is sunk under gold.
The working principle and beneficial effect of this base case are:
The so-called SmF of the present invention3+ LiF is SmF3With the mixture of LiF, the present invention is with SmF3+ LiF is that molten salt system is (molten
Salt system is as reaction medium and electrolytic medium), Sm2O3For electrolyte；The present invention with unpolarizing, can reduce samarium
Deposition potential liquid aluminium (liquid aluminium be fusing after aluminium ingot be made) be cathode.
Due to SmF3+ LiF (especially SmF3) density it is larger, K3AlF6Density it is smaller, so preparation when, first will
SmF3+ LiF molten salt system is dissolved in K3AlF6It is interior, facilitate SmF3The global density of+LiF molten salt system reduce (or " in
With ") under liquid aluminium, make SmF3+ LiF molten salt system is in the top of electrolytic cell, and liquid aluminium is sunken to the bottom of electrolytic cell.
When electrolysis, the aluminium samarium intermediate alloy liquid of generation is attached to cathode (liquid aluminium), that is, the aluminium samarium intermediate alloy liquid generated
It is gradually accumulate in the bottom of electrolytic cell, worker can take out aluminium samarium intermediate alloy liquid by existing equipment, without in order to prepare
Aluminium samarium intermediate alloy and go improve electrolytic cell structure.
In addition, the present invention passes through control SmF3+ LiF and K3AlF6Quality proportioning, make K3AlF6It is not only able to reduce fused salt
System density makes liquid aluminium sink to bottom of electrolytic tank, realizes that product (aluminium samarium intermediate alloy) sinks, additionally it is possible to guarantee Sm2O3?
Melting degree in fused salt influences the electric conductivity of fused salt smaller.
After electrolysis, compared to CN104775137A, (a kind of liquid cathode fused salt electrolysis process prepares the side of aluminium samarium intermediate alloy
Method, current efficiency can reach 90% or more, and Sm content can reach 30% or more (Sm content is aluminium samarium intermediate alloy in aluminium samarium alloy
Ratio shared by middle Sm), though the Sm content and current efficiency of the application decrease, method used by the application is not necessarily to
Worker scoops out the aluminium samarium intermediate alloy liquid on fused salt upper layer, without removing the knot of improvement electrolytic cell in order to prepare aluminium samarium intermediate alloy
Structure is very suitable for industrial mass production application, this is with earlier application before (CN104775137A) or numerous concentrates on making
The theoretical research of standby aluminium samarium intermediate alloy is entirely different.
The present invention uses fluoride system (SmF3、LiF、K3AlF6), pernicious gas will not be generated, it is more environmentally friendly.The present invention
Using Sm cheap and easy to get2O3As electrolysis raw material, production cost can be greatlyd save.
Further, SmF3: mass ratio=75:25-90:10 of LiF, SmF3: the ratio of LiF is in 75:25-90:10 range
When, Sm content is preferable in the current efficiency and product of the application.
Further, Sm2O3Content be fused salt total amount 1-3wt%, can guarantee Sm2O3In SmF3, LiF and K3AlF6In
Preferable solubility.The fused salt total amount of the application meaning is SmF3With LiF mass summation.
Further, the electrolysis temperature of step (3) is 800-900 DEG C, can not only keep high current efficiency, but also can reduce fused salt
Volatilization.
Further, the step (1) further include: preheating is dried to the raw material after weighing respectively, raw material is carried out pre-
Heat can effectively prevent raw material to absorb water.
Further, the drying and preheating temperature of step (1) is 200 DEG C, and the drying and preheating time is 2h.200 DEG C of drying temperature
Preferable drying effect can either be reached, and SmF can also be prevented3It absorbs water with LiF, to prevent other side reactions from occurring.
