ガス状態共凝集法によるマグネシウムリチウム合金生産方法

Japanese Patent JP7381140

B2

The present invention belongs to the technical field of preparation of light metal alloy materials, in particular to a method for producing a magnesium-lithium alloy by a gaseous co-condensation method. The method comprises the steps of: 1) mixing and briquetting a lithium salt, a refractory agent and a catalyst under pressure, and then thermally decomposing to form an unsaturated composite oxide; 2) respectively crushing and ball-milling, and then briquetting the unsaturated composite oxide, magnesium oxide, a reducing agent and a fluxing agent; 3) reducing briquettes in vacuum; 4) making a gas pass through a first condensing chamber of a temperature control device, and then purifying; 5) The purified metal gas is condensed into the condensing phase of the alloy through the second condensing chamber of a quenching device; 6) obtaining the magnesium-lithium alloy with a purity being 99.5% or above by virtue of smelting and flux-refining, and then purifying by distillation. The magnesium-lithium alloy obtained in the present application is not segregated, so that a stable β-phase solid solution or a compound having an increasing purity being 99.95% is formed.
