One common method to determine sulfate as TiO2 involves gravimetric analysis. In this technique, a sample containing sulfate is treated with barium chloride, resulting in the precipitation of barium sulfate. The precipitate is then filtered, dried, and weighed. The weight of the barium sulfate precipitate correlates directly with the amount of sulfate originally present in the sample. To express this as TiO2, a conversion factor based on stoichiometry is applied. This method, while straightforward, can be time-consuming and subject to errors in filtration and drying.

In the world of pigments, titanium dioxide stands tall as a favorite material for its ability to provide brilliant whiteness and exceptional opacity. Its refractive index is high, making it ideal for achieving that pure, lustrous look in paints and coatings. But its capabilities don’t end there; titanium dioxide is also prized for its stability and resistance to discoloration, ensuring longevity in artistic creations and protective layers.
