Synthesis of Ultrafine SrCO3 Powders by High Gravity

摘要：

　　A new synthetic technology of Strontium carbonate with high gravity is introduced in this paper.We got ultrafine SrCO3 powders with Sr(NO3)2 and NaCO3 or CO2 as raw material by high gravity method.We studied flows,the rotating speed,additives and CO2 as the reactants on the morphology of strontium carbonate.The results show that the presence of additive-free,we got rod-like structure of strontium carbonate.Added EDTA,we got a good dispersion of spherical particles of narrow particle size distribution.The presence of EDTA,the average particle size of spherical particles decreases with the speed increases.CO2 alternative Na2CO3 as the reactants,the presence of additive-free,we got the bundle structure of strontium carbonate.The presence of EDTA,we got spherical particles,but the particle dispersion is not well,gathered together.
