| Abstract: | By means of atomic force microscope, the surface pattern, particle size distribution, and specific surface area of La Ti composite oxide were studied. The compound particle surface appears as a smooth sheet, the even size of the compound ranges from 19.85 nm to 25.38 nm. The particle seems smooth, which erects at a height from 4.69 nm to 5.88 nm.The surface area ranges from 58.90 nm 2 to 1 238.04 nm 2. The La Ti composite oxide nanocrystallines enjoy a narrow and even particle size distribution and accumulate closely. |
