图为不同液体石蜡添加量下所得二氧化钛凝胶微球的SEM照片，液体石蜡添加量分别为原油相溶液质量的1%、3%和20%。从图可知，添加液体石蜡对所得二氧化钛粉体形貌无明显影响，所得粉体均为球状结构，且未见明显的团聚。

The picture shows the SEM photos of titanium dioxide gel microspheres with different amounts of liquid paraffin, which are 1%, 3% and 20% of the mass of crude oil phase solution, respectively. It can be seen from the figure that the addition of liquid paraffin has no obvious effect on the morphology of the obtained titanium dioxide powder, and the obtained powder is spherical structure, and no obvious agglomeration is seen.
