Influence of EDTA on the morphology of Barium Carbonate Using High Gravity Technology

引用

Chinese Journal of Structural Chemistry 2012年第10期31卷 1483-1489页

The superfine BaCO3 particles were synthesized by high gravity technology with BaCl·2H2O and Na2CO3 as the raw materials. The changes of particle size and morphology were studied by adding different amount of EDTA, and rod-like, near-spherical and cylindrical shape BaCO3 were prepared. The BaCO3 particles were analyzed and characterized by TG/SDAT, SEM, XRD and FT-IR. The results indicated that the crystal transformation temperature and decomposition temperature of BaCO3 had increased because of EDTA addition. With the increase of EDTA amount, the shape of BaCO3 changed from irregular rod-like to near-spherical then to cylindrical shape. All different shape BaCO3 adopts orthorhombic crystal systems.
