On the basis of mechanism ions precipitation reaction equilibrium, thermodynamic analysis Me n+ (La 3+ , Ni 2+ Fe Al )-CO 3 2- -NH •H 2 O system was discussed in this paper. The relation curves between total concentrations each metal ion and pH values at different ammonia c N carbon C were obtained. suitable value complete for all also determined. It shows that when = 0.010 mol•L -1 1.000 optimal is 9.0 to prepare doped titanium dioxide powders by coprecipitation-coating process using NaHCO NH as precipitants.
