Waste silicon production recycling technology developed in Kazakhstan

Technical silicon is needed for semiconductor manufacturing

News

The "Metallurgy" center of Karaganda Industrial University has developed a method for producing silicon-containing alloys using off-grade raw materials. Tests were conducted on a 250 kVA ore-thermal electric furnace, according to the press service of the Ministry of Science and Higher Education of Kazakhstan.

The goal of the study is to evaluate the effectiveness of the technology for smelting crystalline silicon and ferrosilicon using microsilica.

The research results confirm the possibility of involving secondary material resources in the production cycle. The proposed technology will reduce the volume of metallurgical waste and decrease the environmental burden on the environment.

Kazakhstani scientists tested the technology for smelting technical silicon using a briquetted charge made from microsilica. It can be implemented in industrial production.

The university's press service emphasized that researchers are focused on developing resource-saving technologies, as well as creating a waste-free production cycle. Technical silicon is in demand for creating polymers, manufacturing solar panels, and semiconductors.
