摘要
我国北方某地天然产出的勃姆石矿富含氧化铝,经过适当焙烧可得到以就γ—Al_2O_3为主的物料,用于制备碱式氯化铝,Al_2O_3利用率较高,可降低生产成本,是生产碱式氯化铝的理想原料。
The boehmite ore occ(?)ring at a place in northern China is rich in alumina.It may be transformed by roasting into a material essentially containing γ-Al_2O_3,which can be used to produce basic aluminum chloride with a higher utilixation ratio of Al_2O_3 and at a lower production cost.Therefore,the boehmite ore is an ideal raw material for producing basic aluminum chloride.
