Inorganic Polymers Using Sodium Silicate Liquid Glass. Features of Silicate Polycondensation
- 3 Downloads
The polycondensation of silicates of sodium liquid glass containing silanol groups is studied by thermogravimetry analysis, differential scanning calorimetry, thermomechanical analysis, and IR spectroscopy. The studies are carried out in a temperature range of 100–600°C. The degree of polycondensation depending on the thermolysis conditions is estimated.
