Effect of Crystallization Time on the Hydrothermal

Bauxite reacts with NaOH (caustic soda) to form sodium alu- minate (Na 2 Al 2 O 4 ) while the silica reacts to form a complex compound of Na 2 O∙Al 2 O 3 ∙SiO 2 . Since the silica content of the bauxite used in the study was relatively low, the formation of this compound is negligible.
