The use of waste to development of products has been an increasingly routine practice today. In this work was used rice husk ash from combustion boiler for energy for synthesis of sodium silicate. The silicate was obtained by means of ash fusion with sodium hydroxide at a temperature of 1200°C for 2 hours. For the synthesis of 4A-zeolite was performed hydrothermal reaction of sodium silicate, previously obtained with sodium aluminate and sodium hydroxide. The zeolite obtained was characterized by X-ray fluorescence, X-ray diffraction and scanning electron microscopy. The results have indicated the formation of 4A-zeolite.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
