Utilization of rice husk ash for production of sodium borosilicate glass cullets

Utilization of rice husk ash for production of sodium borosilicate glass cullets The aim of this study is to produce sodium borosilicate cullet by using rice husk ash. For this purpose, rice husk ash was first characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and chemical analyses. Direct fusion is a method in which materials are fused at high temperatures. Sodium borosilicate cullet is generally produced by direct fusion of precisely measured portions of sodium, boron oxide source, and quartz (SiO2). The novelty of this study is that the use of rice husk ash was used as a source of SiO2. To achieve this goal, different batches were prepared and fused at 1000 °C and 1100 °C to produce sodium borosilicates varying in ratio Na2O.2B2O3.nSiO2 (where n:1, 2, and 3). Produced samples were evaluated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicate the formation of amorphous phase and best results were obtained for NBS2 and NBS5 samples melted at 1000 °C. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of the Australian Ceramic Society Springer Journals

Abstract

The aim of this study is to produce sodium borosilicate cullet by using rice husk ash. For this purpose, rice husk ash was first characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and chemical analyses. Direct fusion is a method in which materials are fused at high temperatures. Sodium borosilicate cullet is generally produced by direct fusion of precisely measured portions of sodium, boron oxide source, and quartz (SiO2). The novelty of this study is that the use of rice husk ash was used as a source of SiO2. To achieve this goal, different batches were prepared and fused at 1000 °C and 1100 °C to produce sodium borosilicates varying in ratio Na2O.2B2O3.nSiO2 (where n:1, 2, and 3). Produced samples were evaluated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicate the formation of amorphous phase and best results were obtained for NBS2 and NBS5 samples melted at 1000 °C.
