What is Revealing the Effect of Anions on the Formation and Transformation of Zeolite LTA in Caustic solutions: An In Situ Synchrotron PXRD Study about?
Zeolite LTA is one of the largest industrial zeolites in both volume and market value. Natural resources or manufacturing wastes such as clay minerals, fly ash, and lithium slag are now used as raw materials for the economically and environmentally friendly synthesis of zeolites. However, soluble impurities such as inorganic anions (CO 3 2− , SO 4 2− , and PO 4 3− ) in these feeds have significant effects on the quality of zeolite LTA products, because these impurities enhance or inhibit the formation of other unwanted phases (amorphous zeolites or sodalite) via mechanisms that remain poorly investigated. Here we use in situ synchrotron powder X-ray diffraction to study the effects of different inorganic salts (Na 2 CO 3 , Na 2 SO 4 , and Na 3 PO 4 ) on the kinetics of the sequential phase transformations in zeolite LTA during 2.5 h of reaction at 90 °C in both weakly and highly alkaline solutions. The results show that different salts have no effects on the amorphous phase formation stage but do affect the zeolite or sodalite crystallization stage. The addition of Na 2 CO 3 increases the dissolution rate of zeolite, but it barely promotes the crystallization rate of sodalite. The
