Titanium dioxide (chemical formula: TiO ₂) is a white solid or powdery amphoteric oxide, considered to be the best-performing white pigment in the world. Titanium dioxide has the characteristics of nontoxicity, optimal opacity, optimal whiteness, and brightness. It has strong adhesion, is not prone to chemical changes, has a high melting point, and also has good UV shielding properties.
Titanium dioxide
Rutile is a relatively pure titanium dioxide, generally containing more than 95% titanium dioxide and is an important mineral raw material for extracting titanium, but its reserves in the earth’s crust are relatively small. Rutile is one of the main minerals containing titanium.
The tetragonal crystal system often has intact tetragonal columnar or needle-shaped crystals, with aggregates in granular or dense block form. Dark red, brownish red, yellow or orange-yellow, with iron-rich ones appearing black; Stripes are yellow to light brown. Diamond luster, iron hematite has a semi metallic luster.
It has excellent properties such as high-temperature resistance, low-temperature resistance, corrosion resistance, high strength, and low specific gravity, and it is widely used in military aviation, aerospace, navigation, machinery, chemical industry, seawater desalination, and other fields.
Industrial application: Titanium dioxide is an important white pigment and ceramic glaze. Used in industries such as paint, ink, plastic, rubber, paper, synthetic fibers, watercolor pigments, etc. Titanium dioxide is the whitest thing in the world, and 1 gram of titanium dioxide can paint an area of over 450 square centimeters as white as snow. It is 5 times whiter than the commonly used white pigment, lithopone, making it the best pigment for making white paint. Titanium dioxide used as a pigment in the world produces tens of thousands of tons annually. Titanium dioxide can be added to paper to make it white and opaque, with an effect 10 times greater than other substances. Therefore, titanium dioxide should be added to banknote paper and art paper. In order to lighten the color of plastic and soften the luster of artificial silk, titanium dioxide is sometimes added.
Environmental protection: Titanium dioxide, as a catalyst for light coating pigments, is not only an environmentally safe cleaner but also can save energy and protect environmental resources. Due to its ability to effectively reflect direct sunlight and its stable properties, titanium dioxide has good covering ability. If sprayed in the stratosphere, it can have a long-term effect.
Sunscreen cosmetics: Titanium dioxide is an inorganic component with excellent chemical stability, thermal stability, nonmigration, strong color fading and covering power, low corrosiveness, good dispersibility, and is non-toxic, odorless, and non-irritating. It is safe to use and also has bactericidal and deodorizing effects. More importantly, titanium dioxide can absorb ultraviolet radiation as well as emit and scatter ultraviolet radiation, making it highly resistant to ultraviolet radiation. Compared with the same dose of organic anti-ultraviolet agents, its absorption peak in the ultraviolet region is higher. Moreover, nano titanium dioxide has a blocking effect on both mid-wave and long-wave ultraviolet radiation, unlike organic anti-UV agents, which only have a single shielding effect on mid-wave or long-wave ultraviolet radiation. Especially due to its fine particles and high transparency of the finished product, which can transmit visible light, when added to cosmetics, the skin has a natural whiteness, overcoming the disadvantage of some organic or pigment-grade titanium dioxide being opaque and causing the skin to appear unnatural pale.
