Background technique
Indium is the more expensive dissipated metal of price, and silvery white gloss is presented in indium metal, with the low spy of fusing point higher boiling
Point, and indium metal has the advantages that good ductility, low resistance, plasticity is strong, has good smooth permeability and conduction
Property, it is therefore widely used in science and techniques of defence, wireless telecommunications, the fields such as space flight and aviation, new and high technology.
The impurity element for mainly including in indium metal has Pb, Cd, Tl, Zn, Sn, Cu, Ni etc., in the purification process of indium metal
In, mainly remove the above impurity element.In general, vacuum distillation technique separating indium and copper, need 1000 DEG C of temperature with
Upper temperature just can be achieved.
Summary of the invention
In view of the problems of the existing technology the present invention, provides a kind of method that separating indium copper alloy is evaporated in vacuo, this hair
The bright affinity according to metallic copper, indium and sulphur is of different sizes and indium sulfide is different with the saturated vapour pressure of copper sulfide, indium metal
It forms the sulfide of indium and is volatized into volatile matter, copper segregation realizes the separation of indium metal and copper in condensate.
A method of vacuum distillation separating indium copper alloy, the specific steps are as follows:
(1) indium copper alloy is heated to fusing point or more, addition vulcanizing agent, which is uniformly mixed, obtains mixture A；
(2) under vacuum conditions, by the mixture A of step (1) be at the uniform velocity warming up to temperature be 600 ~ 900 DEG C at distillation separation 30 ~
60min obtains gas phase and liquid phase, and gas phase is the sulfide of indium and the mixture of indium metal, and copper segregation is in condensate liquid phase.
It is calculated in mass percent, indium 10%~99% is contained in the indium copper alloy, remaining is copper.
The vacuum degree is 5~20Pa.
The molar ratio of sulphur and indium in indium copper alloy is (1 ~ 1.2) in the vulcanizing agent: 1.
The vulcanizing agent is elemental sulfur or sulfide.
The beneficial effects of the present invention are:
The present invention according to the affinity of metallic copper, indium and sulphur is of different sizes and the saturated vapour pressure of indium sulfide and copper sulfide not
It together, can be in 600 ~ 900 DEG C of next footworks of low temperature by the indium and copper of indium copper alloy using the method for vacuum distillation separating indium copper alloy
It is completely separated.
