作者以宁夏某地明矾石化埃洛石为原料，通过焙烧活化，分别用H2SO4和NaOH提取所会活性则对Al2O3和SiO2成功地制取了微细a-Al2O3和白炭黑。该研究不但可生产a-Al2O3和白炭黑，还可生产Al2（SO4）3和NH4Al（SO4)2及中低模数的水玻璃，是开发利用含明矾石化埃洛石矿的有效途径。
In this paper, the alum felbronite in a certain area of Ningxia was taken as the raw material and activated by roasting. The activity of H2SO4 and NaOH were respectively extracted to obtain fine a-Al2O3 and silica for Al2O3 and SiO2. The study not only produces a-Al2O3 and silica, but also produces Al2 (SO4) 3 and NH4Al (SO4) 2 and low and medium modulus water glass. It is an effective way to develop and utilize the halloysite containing alum.
