What is titanium dioxide?

The calcined product obtained by the ordinary zinc-barium white preparation method is beaten into a slurry, which is then surface-treated with sodium silicate, aluminum sulfate or sodium aluminate and surfactant, and then filtered, washed, dried and pulverized. Can.

Relative Density Among commonly used white pigments, lithopone has the smallest relative density. Among white pigments of the same mass, titanium dioxide has the largest surface area and the highest pigment volume.

The global Lithopone market size was valued at $169.8 million in 2019, and is projected to reach $218.6 million by 2027, growing at a CAGR of 3.3% from 2020 to 2027.

Lithopone has therefore traditionally been used in stoppers and putties, jointing compounds and sealing compounds, primers and undercoats and in road-marking paints.

Following the filtration, the precipitate is washed thoroughly to remove any impurities and excess reagents. This is a crucial step, as thorough washing ensures that no contaminants interfere with the final mass measurement. Once washed, the precipitate is dried in an oven at a controlled temperature to remove moisture, ensuring that the mass recorded reflects only the titanium content.

The uses and applications of Titanium Dioxide may vary according to its specification. The main forms of Titanium Dioxide are dependent on particle sizes, surface treatment, and crystalline forms.

Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.
