Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.

In the experiment, the growth of iron yellow particles can be inhibited by adding additives, so as to prepare iron oxide yellow cryst

Reasons for listing: Henan Billions Chemical Co., Ltd., a well-known brand of TiO2 factory, a famous trademark in Henan Province, a listed company, a drafting unit of national and industry standards, a high-tech enterprise, advocating the implementation of clean production, focusing on titanium and zirconium fine powder A large-scale inorganic fine chemical enterprise engaged in material R&D and manufacturing.

Above 10%, 1 kg of TiO2 should be replaced by 1.3 kg of Lithopone 30%, reducing the amount of polymer accordingly. 

The whole scientific experimental design in some of these studies is‌ very flawed, Kaminski said.

Relative to a lot of other things that people should be concerned about, titanium dioxide in my mind, is really low on the list. I would be more worried about some substitutes that people are using for titanium dioxide that don't have decades of research associated with it, said Westerhoff.

In their role as risk managers, the European Commission and Member States will now reflect on EFSA’s scientific advice and decide upon any appropriate regulatory measures or advice for consumers.
