Hydrothermal transformation of kaolinite in the system k₂osio₂al₂o₃h₂o
Ríos Reyes, Carlos Alberto; Denver Williams, CraigA kaoliniterich raw material was treated hydrothermally with 1.33 and 3.99M KOH solutions at 100 and 175 °C during different reaction times ranging from 24 to 528 h. The synthesis products were characterized by Xray ...Universidad Nacional de Colombia Revistas electrónicas UN Dyna. -
Synthesis and characterisation of sod-, can-and jbw-type structures by hydrothermal reaction of kaolinite at 200oc
Ríos Reyes, Carlos Alberto; Denver Williams, Craig; Roberts, CliveLow-silica zeolitic materials like SOD, CAN and JBW crystallized after hydrothermal transformation of kaolinite in the system Na₂O–Al₂O₃–SiO₂–H₂O at 200oC, with or without the addition of a structure-directing agent.
