Abstract
The article is devoted to the use of man–made and natural waste, such as silica and rice husk, in the synthesis of silicon carbide (SiC), a key material in demand in various industries. Traditional and alternative methods of SiC production are considered, including waste recycling to create environmentally safe and cost-effective technologies. Special attention is paid to improving the quality of synthesisthrough pretreatment of the starting materials and optimization of the reaction. The results obtained show the high efficiency and promising use of waste in industry, which helps to reduce the environmental burden and increase the sustainability of the metallurgical industry.
