titanium dioxide used in rubber

Moreover, the gravimetric method's inherent accuracy makes it a preferred choice for regulatory compliance. Many manufacturing processes are subject to stringent quality regulations, and having reliable methods for determining material composition is fundamental to meeting these standards. Accurate gravimetric analysis assists manufacturers in minimizing waste, optimizing formulations, and ensuring that end products are both effective and safe.

Titanium dioxide production begins with the extraction of raw materials, typically ilmenite or rutile, from mines. In a white titanium dioxide factory, these minerals undergo a rigorous refining process that includes steps like sulfuric acid digestion, chloride process, or sulfate process, depending on the factory's technology and resources. The resulting titanium dioxide pigment is then purified, dried, and ground to achieve the desired particle size and quality.
