china use of titanium dioxide

One of the most significant uses of titanium dioxide is in the production of paints and coatings. It acts as a pigment that provides brightness, opacity, and durability to the final product. The high refractive index of titanium dioxide allows it to scatter light effectively, making it ideal for creating opaque finishes. Moreover, its chemical stability ensures that the color remains consistent over time, even when exposed to harsh environmental conditions.

In 1970, Japanese scholars studied the phase diagram of iron oxide microcrystalline formation, which laid a theoretical foundation for the preparation method of iron oxide yellow crystal seed. According to the research results, iron yellow crystal seeds can be formed under acidic or alkaline conditions. Because iron yellow is a crystal structure, in order to crystallize into pigment particles, it must first form crystal nucleus and become crystal seed, and then the crystal nucleus grows into iron yellow. Otherwise, only thin and dim color paste can be obtained, which does not have pigment properties. Acid process can be divided into iron sheet process and drop addition process.
