lomon titanium dioxide r996 suppliers

Micronized TiO2 factories employ sophisticated processes that ensure a consistent product with precise particle size distribution. The production process begins with raw ore extraction, followed by beneficiation to remove impurities. The refined ore then goes through a chemical process that converts it into titanium dioxide. This conversion typically involves the sulfate or chloride process, where the ore reacts with sulfuric acid or chlorine gas, respectively.

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.
