Titanium dioxide (TiO₂), commonly known as titanium white, is an inorganic compound that appears as a white, amorphous powder. It is odorless and tasteless, chemically stable, and insoluble in water and most weak acids.
Titanium dioxide (TiO₂), commonly known as titanium white, is an inorganic compound that appears as a white, amorphous powder.
It is odorless and tasteless, chemically stable, and insoluble in water and most weak acids. It is hailed as the “King of White Pigments.” It occurs naturally in minerals such as ilmenite and rutile. After being refined and processed using the sulfuric acid or chlorination methods, it becomes an indispensable core material in both industry and daily life.
Titanium dioxide is used across multiple key industries, with the coatings sector accounting for the largest share at approximately 45%.
It is widely used in interior and exterior architectural paints, automotive topcoats, and industrial anti-corrosion coatings, helping to maintain the coating’s long-lasting whiteness and resist erosion from sun and rain. The plastics industry is its second-largest application area, used in PVC pipes, appliance casings, and food packaging. It not only brightens the color but also enhances the weather resistance of plastics, preventing aging and brittleness.
Additionally, it is used in the paper industry to enhance the whiteness and opacity of high-grade paper; in the personal care sector, it serves as a core physical sunscreen ingredient in products like sunscreen, offering a safe and non-irritating solution; and in the food and pharmaceutical sectors, it functions as a compliant additive for candy coatings and tablet coatings.
The widespread use of titanium dioxide stems from its exceptional properties:
first, its extremely high coverage—1 gram of titanium dioxide can cover approximately 450 square centimeters, far exceeding that of traditional white pigments; second, its high whiteness and stability, ensuring it resists discoloration and aging over time; third, its safety and non-toxicity, having been approved by the United Nations for use in food and personal care products; and finally, its excellent photochemical activity, making it suitable for eco-friendly materials.
From wall paints to everyday cosmetics, from plastic products to food packaging, titanium dioxide quietly enhances our lives and improves product quality, serving as a vital link between industrial production and daily life.
