【 摘 要 】

Multi-group orthogonal experiments cooperating MATLAB stimulation were employed to synthesise antimony-doped tin oxide (ATO) (Sb–SnO 2 )-doped silica (ATO/SiO 2 ) composite powder with high conductivity and dispersivity analysis. Results suggested that the resistivity ranged from 3.9 to 300 Ω cm while the nano-silica doping amount ranged from 0 to 1.5% (mass ratio) under the best parameters of Sb-doped content of 9.5 mol%, 3 precursor wash times, calcination temperature of 750°C, gelling reaction temperature of 45°C and calcination time of 2 h. Both the ATO and ATO/SiO 2 particles were characterised by X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscope studies to prove that the addition of silica could not only increase the specific surface area and resistivity of particles, but also reduce the agglomeration of particles. The relationship between conductivity and dispersion of composite powder (Sb–SnO 2 −SiO 2 ) dominated by different nano-silica content could be simulated by the ‘logistic function model’, which has important guiding significance for the preparation of composite powders with prominent characteristics.
