Physical and chemical properties
White powder.
Soft texture, odorless and odorless white powder, strong covering and coloring power, melting point 1560~1580°C. Insoluble in water, dilute inorganic acids, organic solvents, oils, slightly soluble in alkalis, soluble in concentrated sulfuric acid. It turns yellow when heated, and turns white after cooling. Rutile type (R type) has a density of 4.26 g/cm3 and a refractive index of 2.72. R-type titanium dioxide has good weather resistance, water resistance and is not easy to turn yellow, but the whiteness is slightly worse. anatase type (type A) has a density of 3.84 g/cm3 and a refractive index of 2.55. Type A titanium dioxide has poor light fastness and is not resistant to weathering, but has good whiteness. In recent years, nanoscale ultrafine titanium dioxide (usually 10~50 nm) has semiconductor properties, and has high stability, high transparency, high activity and high dispersion, and has no toxicity and color effect.
Product Use:
Used in paint, ink, plastic, rubber, papermaking, 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 photoresist materials, etc
White inorganic pigments. It is the strongest coloring force among white pigments, with excellent hiding power and coloring fastness, and is suitable for opaque white products. Rutile type is especially suitable for outdoor plastic products, which can give the product good light stability. The anatase type is mainly used for indoor use, but it has a slight blue light, high whiteness, great coverage, strong coloring power and good dispersion. Titanium dioxide is widely used as a pigment for paints, paper, rubber, plastics, enamels, glass, cosmetics, inks, watercolors and oil paints, and can also be used in metallurgy, radio, ceramics, welding rods
