Scientists from the Perm National Research Polytechnic University (PNIPU) have developed advanced glass using a product obtained from the purification of acidic mineral water. The new technology speeds up the glass production process, improves its quality and eliminates defects, the university press service said. This development can significantly increase the transparency and uniformity of the glass melt, which is important for many applications from construction to electronics.
During the research, the team led by Doctor of Technical Sciences Olga Ruchkinova found that the use of a mixture of salts (NH4)2SO4 and Li2CO3 with residue from mineral water treatment promotes faster and more uniform mixing of the glass melt. This reduces the firing temperature by 20-50 degrees Celsius and speeds up the entire process. In addition, the new material improves the properties of glass, making it more resistant to ultraviolet radiation, alkalis, acids, and increases its strength by 1.5-2 times.
It is worth noting that this development not only improves the properties of glass, but also helps reduce environmental pollution. The use of sludge from acid mine treatment prevents the leaching of heavy metals from the soil, which has a positive effect on ecosystems. The research was carried out within the framework of the Priority 2030 program and a positive decision has already been made to grant a patent.
