Utilization of Clear Glass Powder Waste as a Source of Silicon (Si)

Introduction

In recent years, the world has been facing a significant challenge in managing waste, particularly in the industrial sector. The increasing amount of waste generated by human activities has not only caused environmental pollution but also wasted valuable resources. One of the most significant contributors to waste is the glass industry, which produces massive amounts of glass waste every year. However, this waste can be a valuable source of raw materials, particularly silicon (Si), which is widely used in the electronic industry and renewable energy. This article discusses the utilization of clear glass powder waste as a source of silicon (Si) through the magnesiothermic process.

Background

Silicon is a highly sought-after material in the electronic industry, particularly in the production of semiconductors, solar panels, and other electronic devices. However, the production of silicon requires a significant amount of energy and resources, making it a costly and environmentally unfriendly process. In recent years, researchers have been exploring alternative sources of silicon, including glass waste. Glass waste is a significant contributor to waste in the industrial sector, and it is estimated that over 100 million tons of glass waste are generated every year.

Methodology

The study used clear glass powder waste from home industry waste, particularly glass bottles, as the source material. The glass was washed thoroughly to remove dirt and impurities, and then mashed and filtered using a 100 mesh sieve. The mashed glass was then added to chloride acid (HCl) and sulfuric acid (H2SO4) and heated to dissolve the impurities contained in the glass. The resulting silica was then analyzed using Fourier-Transform Infrared Spectroscopy (FT-IR) and X-Ray Diffraction (XRD) techniques.

Results

The results of the FT-IR analysis showed the presence of uptake at 1033.85 cm-1, which indicated the existence of the Si-O-S-si asymmetry group, and at 771.53 cm-1 which showed the Si-O-Si symmetry group. The XRD graph showed that the silica produced had an amorphous structure. The next process was the reduction of silica to silicon through the magnesiothermic method, with the ratio of SiO2 and Magnesium (Mg) being 1: 2. This process was carried out at 800 ° C with variations of heating time for 4 hours, 5 hours, and 6 hours.

Purification of Silicon

After the reduction process, the resulting mixture was purified through three stages using HCl, acetic acid (CH3COOH), and fluoride acid (HF), also by heating at 800 ° C for 3 hours. The purity of silicon was then analyzed using XRD. The results of the XRD analysis showed that the level of purity of silicon varied depending on the length of heating time. For a 4 hour heating time, the purity of silicone obtained was 73.7%. With 5 hours, purity increased to 78.4%, and for 6 hours, purity reached 83.3%.

Discussion

This study shows a great potential in the use of glass waste as a source of silicone. Clear glass, which is often considered as waste, can be processed into valuable raw materials, namely silicon, which is widely used in the electronic industry and renewable energy, such as solar panels. The process used in this study is not only efficient but also environmentally friendly, because it utilizes existing waste.

Furthermore, increasing the purity of silicon through variations of heating time shows the importance of appropriate control in the production process. By finding optimal heating time, we can maximize the results and efficiency of silicon production. Thus, this research not only provides solutions to waste management but also opens new opportunities for the development of silicon-based industries.

Conclusion

In conclusion, this study demonstrates the potential of utilizing clear glass powder waste as a source of silicon (Si) through the magnesiothermic process. The results of this study show that the purity of silicon can be increased through variations of heating time, and that the process is not only efficient but also environmentally friendly. This research provides a new opportunity for the development of silicon-based industries and opens new avenues for the utilization of waste as a valuable resource.

Based on the results of this study, the following recommendations are made:

Further research is needed to optimize the magnesiothermic process and to increase the purity of silicon.
