Titanium dioxide (TiO2) is a versatile compound widely utilized in various industries, particularly in the production of paints, coatings, plastics, and paper. The accurate determination of titanium dioxide content is essential for quality control purposes in these manufacturing processes. Among the various methods available for quantifying TiO2, gravimetric analysis stands out due to its reliability and accuracy. This article explores the gravimetric determination of titanium dioxide, its significance in factory settings, and the technical processes involved.

Yet another study, this one published in 2006 by the International Agency for Research on Cancer said there was insufficient evidence to conclude that titanium dioxide causes cancer. However, the study also categorized the ingredient as a potential human carcinogen.

- Titanium dioxide, a versatile and essential compound, is widely used in various industries due to its unique properties. One of the most significant applications of titanium dioxide is in the manufacturing sector, where it plays a crucial role in producing a wide range of products.
- Apart from these applications, titanium dioxide also plays a vital role in air purification systems by acting as a photocatalyst that helps break down pollutants into less harmful substances. This property makes it an essential component in improving indoor air quality and reducing environmental pollution.
The report also provides detailed information related to the lithopone manufacturing process flow and various unit operations involved in a manufacturing plant. Furthermore, information related to mass balance and raw material requirements has also been provided in the report with a list of necessary quality assurance criteria and technical tests.
The raw material used in this method is FeSO4. In order to maintain the Fe3 + concentration in the reaction medium in a specific range, reducing agent iron sheet is added in the reaction process. Iron yellow crystal seed was added and air was introduced to synthesize iron yellow under certain pH conditions. The method mainly includes two steps: (1) firstly, FeSO4 · 7H2O is used as raw material, NaOH or NH3 · H2O is used as precipitant or pH regulator, and air is used as oxidant to prepare crystal seed; (2) Iron yellow is produced by two-step oxidation with crystal seed, FeSO4, iron sheet and air.

Porcelain White, 32 per cent sulphide, 68 per cent barium sulphate.
The assessment was conducted following a rigorous methodology and taking into consideration many thousands of studies that have become available since EFSA’s previous assessment in 2016, including new scientific evidence and data on nanoparticles.
A European ban of titanium dioxide in food took effect in 2022, but it is still legal for use in food in the U.S.
4. Paper and Textiles
Based on this opinion, the European Commission and the Member States agreed to remove all uses of titanium dioxide as an additive in food. In January 2022, a Regulation withdrawing the authorisation to use titanium dioxide as a food additive in food products was adopted i.e. Commission Regulation (EU) 2022/63.

It is a white crystalline powder, which 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. The density of lithopone is 4.136~4.34/cm3 and it is 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.
