titanium dioxide for paper making factory

The demand for 30-50nm TiO2 powders stems from their enhanced surface area to volume ratio, which amplifies their reactivity and photocatalytic efficiency. This attribute is paramount in applications such as photovoltaics, where these nanoparticles can boost energy conversion rates in solar cells. In the field of environmental remediation, they serve as potent catalysts for degrading pollutants under light exposure. Furthermore, the exceptional transparency and refractive index of TiO2 nanoparticles make them ideal for high-performance coatings and paints, offering improved durability and aesthetic appeal.

  • Manufacturers of rutile titanium dioxide employ different processes to produce this versatile pigment. The two primary methods are the sulfate process and the chloride process. In the sulfate process, ilmenite ore is treated with sulfuric acid to form titanyl sulfate solution, which is subsequently processed into titanium dioxide. This method typically results in a more opaque and durable pigment that is preferred in applications where weatherability is crucial. On the other hand, the chloride process involves treating rutile ore with chlorine gas to produce titanium tetrachloride, which is then refined and oxidized to form titanium dioxide. This method often yields a higher purity product suitable for applications requiring greater brightness and color stability.
