Homogeneous precipitation synthesis of BaCO3 powders with a needle-like morphology

Homogeneous precipitation synthesis of BaCO3 powders with a needle-like morphology AbstractBarium chloride dihydrate, sodium hydroxide and carbamide were used to prepare barium carbonate (BaCO3) powders using the homogeneous precipitation method. The effects of Ba2+ concentration, (NH2)2CO concentration, NaOH concentration, reaction temperature and reaction time on the particle size and yield of product were mainly researched. The structure and the thermal stability of BaCO3 powders prepared were analyzed using scanning electron microscopy (SEM) and thermogravimetry-differential scanning calorimetry (TG-DSC), respectively. The particle size distribution of BaCO3 powders was also characterized using a laser particle size analyzer. The results showed that the BaCO3 powder prepared has high purity with a needle-like morphology. Based on the results mentioned, this method can be applied in an effective and efficient way for BaCO3 powder preparation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Green Processing and Synthesis de Gruyter

Abstract

AbstractBarium chloride dihydrate, sodium hydroxide and carbamide were used to prepare barium carbonate (BaCO3) powders using the homogeneous precipitation method. The effects of Ba2+ concentration, (NH2)2CO concentration, NaOH concentration, reaction temperature and reaction time on the particle size and yield of product were mainly researched. The structure and the thermal stability of BaCO3 powders prepared were analyzed using scanning electron microscopy (SEM) and thermogravimetry-differential scanning calorimetry (TG-DSC), respectively. The particle size distribution of BaCO3 powders was also characterized using a laser particle size analyzer. The results showed that the BaCO3 powder prepared has high purity with a needle-like morphology. Based on the results mentioned, this method can be applied in an effective and efficient way for BaCO3 powder preparation.
