摘　　要：以天然矿物为原料，添加其他化学试剂在微波场中合成了矿物无机凝胶，反应时间由常规的6-8h减至45min，反应温度由230—310℃减至90-95℃。经XRD、DTA、IR和化学成分分析，均表明其特征与天然矿物无机凝胶具有很好的吻合性。The synthetic mineral inorganic gel was prepared by using some natural materials and chemical reagents as raw materials under the action of microwave irradiation. The reaction time and reaction temperature are reduced from conventionally 6 -8h and 230 -310℃ to 45min and 90 -95℃, respectively. The samples axe characterized by XRD, DTA, IR and chemical analysis. The experimental results showed that the properties of the synthetic mineral inorganic gel are the same as those of natural inorganic gel.
