Abstract
An indium oxide-based particle is provided. The indium oxide-based particle has a mono-dispersive and spherical non-crystalline structure (spherical morphology with amorphous phase). The diameter of particle is ranged between 0.10 μm and 0.70 μm, and the content of an indium oxide is ranged between 10.0 percent by mass and 99.9 percent by mass. The indium oxide-based particle is generated by the precursor with indium ion reacting with alpha hydroxyl acid in an aqueous solution with alkali-modifier additive at a constant temperature. The indium-oxide based particle can be further calcinated as a crystalline indium oxide particle.
