Abstract—

We have examined the feasibility of mechanochemically stimulated thermal synthesis of lithium monoaluminates from a boehmite + lithium carbonate mixture with the use of a semicommercial scale ball mill. The effect of mechanical pretreatment of the mixture of boehmite and lithium carbonate on the solid-state reaction between them has been studied using thermogravimetry, in situ X-ray diffraction, room-temperature X-ray diffraction, specific surface area measurements, and particle size analysis. The results demonstrate that mechanical pretreatment of such a mixture with an Al : Li atomic ratio of 1 : 1 in a semicommercial ball mill at a vial rotation rate of 120 rpm for 58 h, followed by heat treatment in air for 4 h at 950°C, allows phase-pure gamma-lithium aluminate to be prepared.

从 AlO(OH) + Li2CO3 混合物机械化学刺激热合成单铝酸锂的可行性

摘要-

我们已经研究了使用半商业规模球磨机从勃姆石 + 碳酸锂混合物机械化学刺激热合成单铝酸锂的可行性。使用热重法、原位 X 射线衍射、室温 X 射线衍射、比表面积测量和粒度研究了机械预处理勃姆石和碳酸锂的混合物对它们之间固态反应的影响分析。结果表明，在半商业球磨机中以 120 rpm 的小瓶转速对这种具有 1 : 1 原子比的 Al : Li 混合物进行机械预处理 58 小时，然后在空气中以 950°热处理 4 小时C，允许制备相纯的γ-铝酸锂。
