Physicochemical Properties
White powder.Soft, odorless and tasteless white powder with strong covering power and tinting power, melting point 1560~1580℃. Insoluble in water, dilute inorganic acid, organic solvent, oil, slightly soluble in alkali, soluble in concentrated sulfuric acid. It turns yellow when heated and turns white when cooled. Rutile type (R type) density 4.26g/cm3, refractive index 2.72. R-type titanium dioxide has the characteristics of good weather resistance, water resistance and not easy to yellow, but the whiteness is slightly worse. Anatase type (A type) has a density of 3.84g/cm3 and a refractive index of 2.55. A-type titanium dioxide has poor light resistance and weathering resistance, but has good whiteness. In recent years, it has been found that nano-scale ultra-fine titanium dioxide (usually 10-50 nm) has semiconductor properties, and has high stability, high transparency, high activity and high dispersibility, without toxicity and color effects.
Product use:
used in paint, ink, plastic, rubber, paper, chemical fiber and other industries; used in welding rods, refining titanium and manufacturing titanium dioxide Titanium dioxide (nanoscale) is widely used in functional ceramics, catalysts, cosmetics and photosensitive materials, etc.
White inorganic pigment. It has the strongest tinting strength among white pigments, with excellent hiding power and color fastness, and is suitable for opaque white products. The rutile type is especially suitable for plastic products for outdoor use, which can endow the products with good light stability. Anatase type is mainly used for indoor use products, but with a slight blue light, high whiteness, high hiding power, strong tinting 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, and can also be used in metallurgy, radio, ceramics, and welding rods.

1. Used as spectral analysis reagent, preparation of high-purity titanium salts, pigments, polyethylene colorants, and abrasives. It is also used in the manufacture of pharmaceutical industry, capacitor medium, high temperature alloy and high temperature sponge titanium.
2. It is used to make titanium dioxide, sponge titanium, titanium alloy, artificial rutile, titanium tetrachloride, titanium oxysulfate, potassium fluorotitanate, aluminum titanium chloride, etc. Titanium dioxide can be used to make high-grade white paint, white rubber, synthetic fibers, coatings, welding rods and rayon, fillers for plastics and high-grade paper, and is also used in telecommunication equipment, metallurgy, printing, printing and dyeing, enamel and other departments. Rutile is also the main mineral raw material for the extraction of titanium. Titanium and its alloys have excellent properties such as high strength, low density, corrosion resistance, high temperature resistance, low temperature resistance, non-toxicity, etc., and have special functions such as gas absorption and superconductivity, so they are widely used in aviation, chemical industry, light industry, navigation, Medical, national defense and marine resources development and other fields. More than 90% of titanium minerals in the world are used to produce titanium dioxide white pigments, and this product is more and more widely used in paint, rubber, plastic, paper and other industries.

Precautions for use
1. Color is an important technical indicator for marking pigments. The color index of titanium dioxide is whiteness. Even titanium dioxide with the same chemical composition will have different colors due to different process routes, raw materials, equipment, technologies, etc. In addition, the factors that often play a decisive role are its particle shape, size, particle size distribution, crystal form, impurity content, etc.
2. Hiding power: The optical nature of hiding power is caused by the difference between the refractive indices of the pigment and the surrounding medium. The refractive index of rutile type titanium dioxide is 2.71 and that of anatase type is 2.55. It is the white pigment with the highest hiding power. The masking effect is mainly due to the scattering caused by titanium dioxide, or the absorption caused by the presence of colored substances, or the above two reasons to reduce the intensity of the incident light, and the masking phenomenon occurs. Therefore, the main reason for determining the hiding power of titanium dioxide is not only the chemical composition and crystal form, but also the particle shape, particle size and particle size distribution of titanium dioxide.
3. Tinting strength: Tinting strength is an important characteristic index of titanium dioxide, that is, after titanium dioxide is mixed with another pigment, the ability of the mixture to display its own pigment can be obtained. That is to say, for a white pigment, after it is mixed with a dark pigment, the lighter the color of the mixture, the stronger its tinting strength.
4. Oil absorption factor: Oil absorption is also one of the important pigment properties of titanium dioxide, because it involves the filling state of titanium dioxide in the vehicle, and can explain its dispersion performance in the medium.

5. Factors of light resistance and weather resistance: The light resistance and weather resistance of titanium dioxide are important indicators to measure the application performance of titanium dioxide. It is meaningless to refer to its light resistance and weather resistance alone. This indicator is meaningful only after titanium dioxide is applied to relevant application fields (such as paint, plastic, etc.). Therefore, the light resistance and weather resistance of titanium dioxide refers to its light resistance and weather resistance in a certain field. In addition, to measure the light resistance and weather resistance of titanium dioxide, it is necessary to ensure that the weather resistance of its application carrier is better than that of titanium dioxide. The main factors affecting the weather resistance index of titanium dioxide are its chemical composition, chemical form of coating material, crystal structure, application formula, etc.
6. Chemical composition factors The chemical composition of titanium dioxide determines the chemical properties of titanium dioxide. It is the main sign of the difference between pigments. In addition to reflecting a series of pigment properties of pigments, such as whiteness, achromatic power, oil absorption, etc. In addition, it also has a great effect on its application performance, such as weather resistance, dispersibility, etc.
7. Volatile matter: The volatile matter of titanium dioxide is actually the water content. Because of the high energy and hydroxyl groups on its surface, its surface always has to adsorb a certain amount of water to reduce its surface energy. The amount of adsorbed water is related to the organic surface treatment of titanium dioxide and the humidity and temperature of the surrounding environment. The level of volatile content of titanium dioxide cannot determine the quality of the product, it depends on its application system. In general, the level of volatile matter in water-based systems has little effect on the application, but for systems such as oil-based systems and polyolefins, the lower the volatile matter, the better.
8. Dispersibility factor Dispersibility is also called grinding dispersibility or grinding wettability. When used in water as a medium, it is called water dispersibility, and when used in solvent and other coating systems, it is called oil dispersibility. The dispersibility index is an important application index of titanium dioxide. The quality of dispersibility not only affects the achromatic power, hiding power, oil absorption and other indicators of titanium dioxide pigments, but also affects the gloss and weather resistance of coating film formation or profile forming. When grinding and dispersing in a paint production plant, the quality of dispersibility directly affects the length of grinding and dispersing time, which is one of the important economic indicators in the production of paints, and if the grinding time is too long, it will increase equipment pollution and make the product whiteness. Difference. In the production of plastic masterbatch or profiles, the quality of dispersion directly affects the replacement cycle of the machine head screen and the performance of the final product.
