CAS 13463-67-7 titanium dioxide

Details:

Superphosphate name
titanium dioxide

Physicochemical Description
Density: 4.26 g/mL at 25 °C(lit.)
Boiling point: 2900 °C
Melting point: 1840 °C
Molecular formula: O2Ti
Molecular weight: 79.866
Flash point: 2500-3000°C
Exact quality: 79.937775
PSA: 34.14000
Appearance: powder
Refractive index: 2.61
Storage conditions: Store in a cool, ventilated warehouse. The package is sealed. Can not be stored and transported together with acid products.
Stability:
1. It can be dissolved in concentrated sulfuric acid and hydrofluoric acid by boiling for a long time. It reacts with molten sodium hydroxide to generate titanate. At high temperatures, it can be reduced to low-valent titanium compounds by hydrogen, carbon, metallic sodium, etc., and react with carbon disulfide to generate titanium disulfide. The refractive index of titanium dioxide is the largest among white pigments. The rutile type is 8.70 and the anatase type is 2.55. Since both anatase and brookite-type titanium dioxide will transform into rutile-type at high temperature, the melting point and boiling point of brookite-type and anatase-type titanium dioxide are practically non-existent. Only rutile titanium dioxide has a melting point and boiling point. The melting point of rutile titanium dioxide is 1850°C, the melting point in air is (1830±15)°C, and the melting point in oxygen enrichment is 1879°C. The melting point is related to the purity of titanium dioxide. The boiling point of rutile titanium dioxide is (3200±300)K, and titanium dioxide is slightly volatile at this high temperature.
Water solubility: insoluble

Handling and storage
Store at +5°C to +30°C.

Folkore Uses
Use 1: Used in paint, ink, plastic, rubber, paper, chemical fiber and other industries.
Use 2: Edible white pigment; compatibilizer. Silica and/or alumina are commonly used as dispersing aids.
Use 3: White inorganic pigments. It is the strongest coloring power among white pigments, has excellent hiding power and color fastness, and is suitable for opaque white products. The rutile type is especially suitable for plastic products used outdoors, and can give the products good light stability. Anatase is mainly used for indoor products, but it has a slight blue light, high whiteness, large hiding power, strong coloring power and good dispersion. Titanium dioxide is widely used as a pigment for paint, paper, rubber, plastic, enamel, glass, cosmetics, ink, watercolor and oil paint. It can also be used in the manufacture of metallurgy, radio, ceramics, and welding electrodes. In recent years, it has been discovered that nano-sized titanium dioxide has certain special uses, such as sunscreen cosmetics, wood protection, food packaging materials, agricultural plastic films, natural and man-made fibers, transparent exterior durable topcoats and effect pigments, and can also be used as high-efficiency Photocatalysts, adsorbents, additives for solid lubricants, etc.
Use 4: As a food coloring agent, my country stipulates that it can be used in preserved fruit, the maximum use amount is: 10g/kg; in candy coating, the maximum use amount is 2.0gkg.
Use 5: Used in paint, plastic, rubber and other industries
Use six: 1. Uniform particle size and good dispersion; 2. Basically no scattering effect on incident visible light, with strong UV shielding ability and excellent transparency. As a new type of material, it has been widely used in cosmetics, coatings, and paints. In other products; 3. Applied to plastic, rubber and functional fiber products, it can improve the anti-aging ability, anti-chalking ability, weather resistance and strength of the product, while maintaining the color and gloss of the product, and extending the life of the product; 4. Used in inks, coatings, textiles, can improve its adhesion, anti-aging, scrub resistance; 5. Lipophilic, can be well dispersed in organic solvents and plastic resins; 6. Used in papermaking In industry, it can improve printability and impermeability; 7. It can also be used in metallurgy and aerospace industry.
Use 7: Preparation of a certain concentration of titanium compound standards, pigments, ceramic industry, 4N-grade titanium dioxide used to prepare high-temperature alloys, high-temperature sponge titanium raw materials.
