By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Ceramics have been published. According to news reporting originating in Osaka, Japan, by VerticalNews journalists, research stated, "Synthesis of zeolite A from aluminoborosilicate glass used in liquid crystal display (LCD) panel glass substrate was attempted. Mixture of aluminoborosilicate glass and sodium aluminate was hydrothermally treated with sodium hydroxide solution for 10.8-345.6 ks at 368-423 K. Aluminoborosilicate glass was also acid treated with nitric acid before hydrothermal treatment."
The news reporters obtained a quote from the research from Osaka Prefecture University, "Obtained samples were characterized by X-ray diffraction and scanning electron microscope observation. Zeolite A, hydroxysodalite, and zeolite P were synthesized, and with the specific conditions of hydrothermal treatment, a single phase of zeolite A was successfully obtained. Acid treatment was effective for synthesis of a single phase of zeolite A, because the components of aluminoborosilicate other than SiO2 preferentially eluted for acid solution and during following hydrothermal treatment SiO2 was supposed to elute for alkaline solution. Cation-exchange capacities (CECs) were investigated for these products. It was clarified that CEC of the product with a single phase of zeolite A obtained from aluminoborosilicae glass was 4.2 mol/kg. CEC of the product consisted of zeolite A and hydroxysodalite was 3.9 mol/kg, and the one consisted of zeolite A, hydroxysodalite, and zeolite P was 2.6 mol/kg."
According to the news reporters, the research concluded: "This results shows that aluminoborosilicate glass could be expected to be recycled in zeolite A with good CEC by the appropriate process."
