china tr 52 titanium dioxide

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.

White crystalline powder. It is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger the hiding power and the higher the quality. Density 4.136~4.34 g/cm3, insoluble in water. It easily decomposes when exposed to acid to produce hydrogen sulfide gas, but does not work when exposed to hydrogen sulfide and alkaline solutions. It turns into light gray after being exposed to ultraviolet rays in the sun for 6 to 7 hours, but it still returns to its original color when placed in a dark place. It is easy to oxidize in the air and will agglomerate and deteriorate when exposed to moisture.
