Hydrothermal Synthesis of Corrensite: A Study of the Transformation of Saponite to Corrensite
Chlorite Corrensite Hydrothermal Synthesis Randomly Interstratified Chlorite-Smectite Saponite X-ray Diffraction
2011/12/7
Abstract: Hydrothermal synthesis experiments were conducted to study the transition from smectite to corrensite. A mixture of oxides with the bulk composition of corrensite—Na0.4(Si6.4Al1.6)(Mg7..8Al1...
Synthetic gel and glass of illitic composition, natural kaolinite, and mixed-layer illite-smectite were used as starting materials for hydrothermal synthesis of ammonium illite.Ammonium illite was pre...
