Titanium Dioxide
White amorphous powder. There are three variants of titanium dioxide in nature: rutile is a tetragonal crystal; Anatase is a tetragonal crystal; The perovskite is an orthogonal crystal. Mild heat turns yellow, while strong heat turns brown. Insoluble in water, dilute sulfuric acid and organic solvents, soluble in concentrated sulfuric acid,slightly soluble in alkali. Boiling for a long time can dissolve in concentrated sulfuric acid . The boiling point of rutile type titanium dioxide is (3200 ± 300) K, and at this high temperature, titanium dioxide is slightly volatile.

Purpose
Used as a spectral analysis reagent, preparation of high-purity titanium salts, pigment, polyethylene coloring agent, and grinding agent. It is also used in the pharmaceutical industry, capacitor media, high-temperature resistant alloys, and high-temperature resistant sponge titanium manufacturing.
Used for producing titanium dioxide, sponge titanium, titanium alloys, artificial rutile, titanium oxysulfate, potassium fluotitanate, aluminum titanium chloride, etc. Titanium dioxide can be used to produce high-grade white paint, white rubber, synthetic fibers, coatings, welding rods, as well as reducing agents for artificial silk, fillers for plastics and high-grade paper. It is also used in telecommunications equipment, metallurgy, printing, dyeing, enamel and other departments. Rutile is still the main mineral raw material for extracting titanium. Titanium and its alloys have excellent properties such as high strength, low density, corrosion resistance, high temperature resistance, low temperature resistance, and non toxicity. They also have special functions such as gas absorption and superconductivity, making them widely used in aviation, chemical industry, light industry, navigation, medical, national defense, and marine resource development. More than 90% of the world's titanium minerals are used to produce titanium dioxide white pigments, and this product is increasingly widely used in industries such as paint, rubber, plastics, and paper.
