China Inorganic Chemicals Low price per kg Rutile Grade tio2 titanium dioxide

Physical data: 

White powder.

Soft texture, odorless and tasteless white powder, strong hiding power and coloring 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 again after cooling. Rutile type (R type) has a density of 4.26g/cm3 and a refractive index of 2.72. R-type titanium dioxide has better weather resistance, water resistance and not easy to turn yellow, but the whiteness is slightly worse. Anatase (Type A) has a density of 3.84g/cm3 and a refractive index of 2.55. Type A titanium dioxide has poor light resistance and weathering resistance, but its whiteness is good. In recent years, it has been discovered that nanometer ultrafine titanium dioxide (usually 10-50 nm) has semiconductor properties, and has high stability, high transparency, high activity and high dispersion, without toxicity and color effects.

Used in paint, ink, plastic, rubber, paper, chemical fiber and other industries; used in welding electrodes, refining titanium and manufacturing titanium dioxide. Titanium dioxide (nano-level) is widely used in white inorganic pigments such as functional ceramics, catalysts, cosmetics and photosensitive materials. 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 for metallurgy, radio, ceramics, welding rods.
