Hydrothermal synthesis and characterization of a layered zirconium silicate
Generally, the mixed octahedra–tetrahedra zirconium silicates have a negatively charged framework that requires balancing positive ions. Similar to the metal silicate ETS-10, alkaline metals such as Na + and K + in umbite or alkaline earth Ca 2+ in lovozerite can stabilize the structure of zirconium silicates [11], [12].
