fumed titanium dioxide manufacturers

The factory's production process is a testament to precision and optimization. Raw materials, primarily ilmenite, rutile, and anatase ores, undergo a rigorous refining process that includes crushing, leaching, and solvent extraction methods. These steps ensure the purity and consistency required for high-quality pigments. Following this, gaseous chlorination converts the refined ore into titanium tetrachloride, setting the stage for the final synthesis of titanium dioxide through the oxidation of titanium tetrachloride in a heated environment.

The allure of TIO2 lies in its exceptional optical properties. As a pigment, it boasts unrivaled refractive index values, making it an ideal candidate for creating bright, opaque finishes. When incorporated into paints, TIO2 amplifies the reflectance of light, thereby reducing the need for additional layers and saving on material costs. Its ability to scatter all wavelengths of visible light uniformly ensures that the resultant hues are pure and vibrant, transcending the limitations of traditional pigments.

In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”
