从海泡石制备纤维状硅胶及均分散Mg(OH)2

THE PREPARATION OF FIBRED SILICA GEL AND HOMOGENEOUS DISPERSED Mg(OH) 2 FROM SEPIOLITE.

采用盐酸浸泡海泡石制得了具有独特纤维形态的硅胶，考察了镁的溶出率与产物比表面之间的关系，副产的酸浸取液精制后用通氨法制备均分散Ｍｇ（ＯＨ）２。

The specific fibred silica gel has been obtained by extracting sepiolite with hydrochloric acid.The relationship between the dissolving ratio of magnesium and the specific surface of the product has been studied.The homogeneous dispersed Mg(OH) 2 has been got by adding NH 3 to the purified acid-extracted solution. 〖WT5HZ]
