超细高纯硅酸铝生产新工艺研究

Study on preparation of ultra-fine and high purity aluminium silicate

本工艺采用萃取法净化工业硫酸铝 ,稀释沉降法净化水玻璃溶液 ,在添加剂存在下合成超细高纯硅酸铝。

Ultra fine and high purity aluminium silicate was prepared by the reaction of aluminium sulfate and water glass.It was studied that extraction and subsidence methods were used to remove impurities from raw feed.The experimental result shows that the products approach the grade of Degauss Co.,Germany.
