| 摘 要： | Sb-doped SnO2 ultrafine powders were prepared via oxidation-coprecipitation. Also the relation between surface characteristic (i.e. charged status and solvation) and precursor separation was studied. The results showed that the filter washing speed of precursor can be improved by reduced Precursor |ζ| values or lessen Precursor solvation. For example, adding to little organic solvents (such as ethanol )in Washing liquid morely accelerates to separation speed of precursor. This method and principle of washing and separation precursor can be used by other nona powders preparation with precipitation method, also sb doped SnO2 ultrafine powders will be prepared easily in industry with it.
