Manufacture of Nanosilicon from Natural Sand Tanjung Tiram Sub-district of Asahan Regency in Magnesiotermic with the Addition of Sodium Chloride as a Heat Absorber
Introduction
The increasing demand for nanosilicon has led to the development of various methods for its synthesis. One of the most promising methods is the magnesiothermic reduction of silica, which has been shown to produce high-quality nanosilicon particles. However, the use of this method requires careful control of temperature and heating time to prevent the formation of agglomerates and to achieve uniform particle size. In this study, we report the synthesis of nanosilicon from natural sand originating from Tanjung Tiram District, Asahan Regency, using the magnesiothermic method with the addition of sodium chloride as a heat absorber.
Materials and Methods
The natural sand used in this study was obtained from Tanjung Tiram District, Asahan Regency. The sand was first mashed and isolated to obtain silica. The silica was then ultrasonicated with sodium chloride in a molar ratio of 1:10 to ensure that the sodium chloride could function optimally as a heat absorber. The resulting silica was then reduced twice using magnesium with a molar ratio of 1:2. In the first reduction, the silica was heated at 800°C for 6 hours, and in the second reduction, the silica was again heated at the same temperature for 7 hours.
Results
The resulting nanosilicon particles were analyzed using a diffractometer and transmission electron microscope (TEM). The results showed that the nanosilicon particles produced after 6 hours of reduction had a purity level of 49.4% with a particle size ranging from 42,585 Nm to 61,064 Nm. However, the TEM analysis showed that the particle size was uneven. In contrast, the nanosilicon particles produced after 7 hours of reduction had a lower purity level of 29% with a particle size ranging from 47,180 nm to 62,585 nm.
Discussion
The use of sodium chloride as a heat absorber in this process is crucial in controlling the temperature and heating time to prevent the formation of agglomerates and to achieve uniform particle size. The results of the analysis show that the longer the reduction time, the lower the purity obtained, which indicates the possibility of the particle's magic process. The use of magnesium as a reduction agent is also an interesting alternative because it is relatively cheaper and more easily accessible.
Conclusion
The synthesis of nanosilicon from natural sand using the magnesiothermic method with the addition of sodium chloride as a heat absorber is a promising approach for the production of high-quality nanosilicon particles. However, further research is needed to optimize the molar ratio between silica and magnesium, as well as regulating time and reduction temperature to improve the quality of the nanosilicon produced. The results of this study can be a reference for the development of nano material technology in Indonesia, while increasing the added value of local natural resources.
Future Research Directions
Further research is needed to optimize the molar ratio between silica and magnesium, as well as regulating time and reduction temperature to improve the quality of the nanosilicon produced. Additionally, the use of other heat absorbers, such as potassium chloride, should be investigated to determine their effectiveness in controlling the temperature and heating time. The development of a more efficient and cost-effective method for the synthesis of nanosilicon is also essential for the widespread adoption of this technology.
Environmental Impact
The use of natural sand as a starting material for the synthesis of nanosilicon is an environmentally friendly approach because it utilizes local resources and reduces the need for imported materials. Additionally, the use of magnesium as a reduction agent is also an environmentally friendly approach because it is a relatively cheap and easily accessible material. The development of this technology can also contribute to the reduction of greenhouse gas emissions and the conservation of natural resources.
Economic Impact
The development of this technology can also have a significant economic impact by creating new job opportunities and stimulating economic growth. The production of nanosilicon can also contribute to the development of new industries and products, such as electronics, energy storage, and biomedical applications. The increased demand for nanosilicon can also lead to the development of new markets and trade opportunities.
Conclusion
In conclusion, the synthesis of nanosilicon from natural sand using the magnesiothermic method with the addition of sodium chloride as a heat absorber is a promising approach for the production of high-quality nanosilicon particles. Further research is needed to optimize the molar ratio between silica and magnesium, as well as regulating time and reduction temperature to improve the quality of the nanosilicon produced. The results of this study can be a reference for the development of nano material technology in Indonesia, while increasing the added value of local natural resources.
