Twice as strong: Perm creates glass from acid mine cleaning product

New development has accelerated glassmaking

The Perm National Research Polytechnic University (PNRPU) has developed glass from a product for cleaning acidic mine waters. This was reported in the press service of the university.

The development speeds up the process of creating glass.

As a result, the material used affects the composition, changes the viscosity and increases the mixing of the glass melt due to chemical reactions. It generally significantly speeds up the cooking process, and also reduces the temperature at which the process of clarification and homogenization of the glass is completed, by 20-50 degrees Celsius.

To improve transparency and achieve glass homogeneity, scientists obtained a mixture of salts (NH4) 2 SO4 and Li2CO3. This made it possible to significantly speed up the process of cooking silicate glasses. Experts also used sediment from the treatment of acidic mine waters, which will reduce environmental pollution.

The glass made in this way has increased permeability to ultraviolet rays, resistance to alkalis, acids and cracking, as well as increased strength by 1.5-2 times.

The new material can be used in glassmaking all year round in any region of the country.

Earlier www1.ru reported that glazing for Russian MS-21 and SJ-100 aircraft will be produced even faster.
