EDTA对超临界二氧化碳法制备碳酸钡粒子形貌影响的研究
Influence of EDTA on the Morphology of Barium Carbonate Using Supercritical Carbon Dioxide Method
摘要
Abstract
Using Ba(OH), and CO2 gas as raw materials, adding EDTA as control agent, columnar, rodlike, axiolitic and sphere barium carbonate particles were synthesized by supercritical carbon dioxide method. The particles was Characterized by TG/DSC, SEM, XRD and FT-IR. the results indicated that the different morphology barium carbonate particles belong to the orthorhombic crystal system. The mechanism of the morphology control of barium carbonate had been discussed.关键词
