微波制备均分散定组成Mg_5(CO_3)_4(OH)_2·4H_2O

Preparation of monodispersed Mg 5(CO 3) 4(OH) 2·4H 2O with stable composition by microwave method

采用微波处理ＭｇＣＯ３·３Ｈ２Ｏ，制得了具有稳定组成的Ｍｇ５（ＣＯ３）４（ＯＨ）２·４Ｈ２Ｏ，并对微波作用机理进行了初步探讨。该法操作简便、准确，产品性能优于水浴加热或水蒸气加热所得产物。

This paper studied the principle of microwave action and prepared the product of Mg 5(CO 3) 4(OH) 2·4H 2O having stable composition by treatment of MgCO 3·3H 2O suspension with microwave. The product obtained was monodispersed in fine particles whose properties were superior to those prepared by vapour heating and water bath methods.
