硅酸溶胶的凝聚受微波辐射的影响

The Influence of Microwave Radiation on the Gelation of Silicic Acid Sol

采用沉淀法结合微波照射对硅酸溶胶进行凝聚实验,发现在相同条件下利用微波照射可以大大加快硅酸溶胶的凝聚速度。通过物理参数的对比测定,得到了在微波辐射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 experim ent 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 with conventional method. We found that the silicic sol particles formed under micro-wave radiation have bigger specific surface area and stronger absorption ability.
