Descrizione

Applicazioni

• The Study′s Chemical Interaction of the Sodium Silicate Solution with Extender Pigments to Investigate High Heat Resistance Silicate Coating.: This research focuses on the geopolymerization process between sodium silicate solution and extender pigments (ZnO, TiO2, Fe2O3, CaCO3, and Na2SiF6). The study utilizes Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), and X-ray diffraction (XRD) to analyze the chemical interactions. Findings indicate enhanced thermal stability of the coatings, making them suitable for high-temperature applications (Le et al., 2021).
