Titanium is a chemical element with the chemical symbol Ti and atomic number 22. It is located in the fourth period of the periodic table, in group IVB. It is a silver-white transition metal characterized by its lightweight, high strength, metallic luster, and resistance to wet chlorine gas. The most common compound of titanium is titanium dioxide, which is used to produce white pigments. In the past, people used to mine titanium ore primarily to obtain titanium dioxide.
1. The Nature of Titanium Dioxide
二酸化チタン (chemical formula: TiO2) is a white amphoteric oxide with a molecular weight of 79.83. Titanium dioxide is a compound made of titanium, a pure substance consisting of two or more elements (different from elemental matter). A compound has specific properties that are distinct from the elements or ions it comprises, as well as from other compounds. Crystal forms play a significant role in defining these properties. For instance, TiO2 exhibits three primary crystal forms: rutile type, anatase type, and plate titanium type. In terms of optical properties, TiO2 nanoparticles have the ability to scatter and absorb ultraviolet light, providing them with strong ultraviolet shielding capabilities. Ultrafine titanium dioxide powder is frequently integrated into textile fibers as a sunscreen. It is also included in sunscreen creams to enhance cosmetic sunscreens. 二酸化チタン (TiO2) has a high melting point and is also used in the manufacturing of fire-resistant glass, glaze, enamel, clay, and high-temperature-resistant experimental vessels. TiO has high gloss and hardness, and it offers the best opacity, optimal whiteness, and brightness. It can be used as a matting agent for white inorganic pigments and enamels. The performance of TiO2 with semiconductors is very important for the electronics industry. The industrial field utilizes these characteristics to produce electronic components, such as ceramic capacitors. It can also be used in paints, インク, プラスチックス, rubber, paper, 化学繊維, watercolor paints, and other industries. Titanium dioxide is the whitest substance globally, five times whiter than the commonly used zinc white pigment, making it the optimal choice for white paint. Titanium dioxide can be added to paper to improve its whiteness and opacity, with an impact that is 10 times greater than that of other substances. そこで, titanium dioxide is added to banknote paper and art paper. In order to lighten the color of the plastic and make the rayon soft, it is sometimes necessary to add titanium dioxide. Titanium dioxide is the primary component in the surface coating of the electrode. It is a good slagging agent, deoxidizer, diluent, binder, and stabilizer for flux. The slag of the electrode, which is made of low melting point material, has low viscosity and can be utilized for both AC and DC applications. During operation, the arc is fast and stable, the slag is easy to remove, resulting in beautiful welds with good mechanical performance. Ultrafine titanium dioxide has excellent UV shielding and transparency, making it widely used in cosmetics, food packaging plastics, rayon, and natural fibers.
2. Food Application: The US Food and Drug Administration stipulate that TiO2 can be used as a white pigment in all food products. The pigment additive titanium dioxide can be safely used in various colored foods, such as preserved fruits, jellies, fried foods, cocoa products, and similar items. 3. Medical Applications It is suitable for the manufacture of opaque capsules, tablet film coatings, creams, medicinal packaging materials, and pharmaceutical inks. It has the advantages of uniform particle size and good dispersibility. It can be used as a white coloring agent to prepare film coating suspensions, sugar coatings, and gelatin capsules. It can also be mixed with other coloring agents. It can be used as a white coloring agent in the dispersion of granular water and gelatin. A dermatological preparation can also be used as an excipient for a drug instead of starch. 4. Application of titanium dioxide (TiO2) in environmental protection can purify air, provide antibacterial properties, and deodorize. Environmentally harmful gases can be classified into indoor pollutants and atmospheric pollutants. The indoor harmful gases mainly include formaldehyde released from decorative materials, as well as methyl mercaptan, hydrogen halide, and ammonia produced in the living environment. TiO2 can decompose and oxidize substances adsorbed on the surface through photocatalysis, thereby reducing the concentration of these substances in the air and alleviating environmental discomfort. Titanium dioxide has garnered significant attention and is widely used for its excellent catalytic performance, stable chemical properties, environmental friendliness, non-toxicity, and long service life. Titanium dioxide has a promising market outlook for the future.
