Partial substitution of titanium dioxide in liquid paints
- faible abrasivité grâce à une dureté faible
- In the sulfate process, the ore is first crushed and then heated with sulfuric acid. This reaction produces titanyl sulfate, which is subsequently treated with water to form titanium dioxide. The resulting precipitate is filtered, washed, dried, and calcined to produce the final product. One of the drawbacks of this method is the large amount of waste acid generated, which requires careful disposal to minimize environmental impact.
It has an extremely high melting point of 1 843ºC and boiling point of 2 972ºC, so occurs naturally as a solid, and, even in its particle form, it is insoluble in water. TiO2 is also an insulator.

In addition to these uses, titanium dioxide is also used in:
A safety review conducted by the EFSA in 2021 assessed thousands of studies published on titanium dioxide.

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies.[2] The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.[3] Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.[1]
Safety[edit]
“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
We even use titanium dioxide when brushing our teeth as it’s found in many toothpastes.
Used for coloring paint, ink, rubber, etc. Inorganic white pigments are widely used as white pigments in plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyformaldehyde, as well as paints and inks. It is less effective in polyurethane and amino resins, and less suitable in fluoroplastics. It is also used for coloring rubber products, papermaking, varnished cloth, oilcloth, leather, watercolor paints, paper, enamel, etc. Used as an adhesive in the production of electric beads.

Overwhelmingly, research that’s relevant to human eating patterns shows us that E171 is safe when ingested normally through foods and drugs (1,2).

The US and Canada, however, approve the use of titanium dioxide as a food additive. Canada's recent review of titanium dioxide reconfirmed its safety and pointed out that many of the toxicity studies the EU reviewed were not relevant to the safety of titanium dioxide as a food ingredient, and that the ban is based on an abundance of caution and uncertainty.

In food, titanium dioxide has a few different uses. Most notably, its food-grade form is used as a colorant to enhance and brighten the color of white foods such as dairy products, candy, frosting, and the powder on donuts. For foods that are sensitive to UV light, titanium dioxide is used for food safety purposes to prevent spoilage and increase the shelf life of food.
