Titanium dioxide

Titanium dioxide is known as Titanium Dioxide, a dye and pigment with a molecular formula of TiO2 and a molecular weight of 79.8658.
Uses: 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-scale) widely used in functional ceramics, catalysts, cosmetics and photosensitive materials such as white inorganic pigment. It is the strongest coloring agent in white pigments. It has excellent hiding power and color fastness and is suitable for opaque white products. The rutile type is particularly suitable for use in outdoor plastic products, which impart good light stability to the product. The anatase type is mainly used for indoor use products, but has a slight blue light, high whiteness, large hiding power, strong tinting strength and good dispersibility. Titanium dioxide is widely used as paint, paper, rubber, plastic, enamel, glass, cosmetics, ink, watercolor and oil paint. It can also be used in metallurgy, radio, ceramics and welding electrodes.
Nature: white powder.
Soft, odorless and odorless white powder with strong hiding power and tinting strength, melting point 1560 ~ 1580 °C. Do not dissolve in water, dilute mineral acid, organic solvent, oil, slightly soluble in alkali, soluble in concentrated sulfuric acid. It turns yellow when it is hot, and turns white after cooling. The rutile type (R type) has a density of 4.26 g/cm 3 and a refractive index of 2.72. R-type titanium dioxide has good weather resistance, water resistance and yellowing resistance, but the whiteness is slightly poor. The 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 resistance and is not weather resistant, but whiteness is good. In recent years, nano-sized ultrafine titanium dioxide (usually 10 to 50 nm) has been found to have semiconducting properties, and has high stability, high transparency, high activity and high dispersibility, and no toxicity and color effect.
