Abstract:Chemical co-precipitaton method was used to prepare indium tin hydroxide with cubic lattice. The cubic crystal structure transformed to amorphous after heat treatment at 250 ℃ for 1 h. When the heat treatment temperature was higher than 280 ℃, the amorphous transformed to indium tin oxide with cubic crystal structure. After heat treatment at 600 ℃ for 1 h, the particle size is 8～20 nm, the mass ratio of In/Sn is near 9∶1, the granules have spherical shape and the dispersity is good.
Key words: indium tin oxide nanophase powder microstructure
