Researchers from the Siberian Federal University (SFU), together with colleagues from the Institute of Space Technology of the KSC SB RAS, have developed a technology for producing high-strength glass from mining waste. This material can be used in construction, aviation, and the space industry.
Instead of expensive purified chemicals, scientists used available natural rocks, such as dunite and limestone. This made it possible not only to reduce the cost, but also to reduce energy consumption due to the lower melting point.
The new glass-ceramic material (sitall) is transparent to visible and infrared light, and also has increased strength due to microscopic crystals that strengthen the structure. Such materials are widely used in aggressive environments, from laboratories to rocket skin.
Reserves of ore raw materials that meet the requirements of the glass industry are being depleted. We have proposed an alternative - waste recycling
The technology allows recycling industrial waste, reducing the cost of glass and reducing the environmental burden. This is a step towards sustainable production and the development of space and construction technologies based on available raw materials.
