The article shows how the rice husk, which is the final waste of rice processing production, can be obtained from silicon dioxide of various degrees of yield, processed under different temperature conditions. As a rule, such waste is incinerated or can be simply thrown out. the smoke emitted from the incineration of such waste can negatively affect the environment and lead to pollution. Currently, due to the development of modern electronic technologies, amorphous silicon dioxide has a high use. In this work, the issues of obtaining amorphous silica were considered. The methods, such as, X-ray diffraction, infrared spectral and scanning electron microscopy were used to determine characteristics of obtained silica. In this paper, the purity and structure of silicon dioxide are determined.
