Improvement of the Method for Nanometer PbCO3 Powders Preparation
Abstract:
The structural and morphological investigations of the products PbCO3 by common preparation method showed that the PbCO3 crystal grows very quickly and nanometer PbCO3 could hardly be obtained. The nanometer PbCO3 was synthesized by mixed Pb(CH3COO)2·3H2O and Na2CO3 in 8 000 r/min quick mixing equipment. The influences of material and concentration of reactant on the preparation of nanometer PbCO3 were discussed. The nanoparticles as prepared showed narrow size distribution and the particle sizes of PbCO3 were about 10~30 nm when Pb(NO3)2 was replaced by Pb(CH3COO)2·3H2O as raw material, and the particle sizes of PbCO3 decreased with increasing the concentration of Pb(CH3COO)2·3H2O.
