摘要
采取沉淀法结合微波照射对硅酸溶胶进行胶凝实验，发现在相同的条件下利用微波照射可使硅酸溶胶的凝聚速度大大加快。通过物理参数的对比测定，得到了在微波辐照下凝聚所产生的硅胶粒子具有更大的表面积和更强的吸附能力。
It is our endeavour to do gelation experiment on silicic acid sol by means of sedimentation with microwave radiation. Under the same conditions, the gelation rate of silicic acid sol with microwave radiation is much faster than that by conventional method. We found that the silicic sol particles formed under microwave radiation have bigger specific surface area and stronger adsorption ability.
