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.

The resulting titanium dioxide must meet stringent quality standards. It is tested for properties such as particle size, crystal structure, and impurity levels, as these characteristics significantly impact its performance in end products. For instance, in paints, the particle size affects hiding power and durability, while in food colorants, purity is paramount to ensure safety and compliance with regulatory standards For instance, in paints, the particle size affects hiding power and durability, while in food colorants, purity is paramount to ensure safety and compliance with regulatory standards For instance, in paints, the particle size affects hiding power and durability, while in food colorants, purity is paramount to ensure safety and compliance with regulatory standards For instance, in paints, the particle size affects hiding power and durability, while in food colorants, purity is paramount to ensure safety and compliance with regulatory standardstitanium dioxide is prepared from suppliers.
