Chemical properties of titanium is the main rutile one of minerals. The four winds of crystal, often with four square column in the form or needle crystal shape, a collection of granular or density blocks. Dark red, brown red, yellow or orange, iron rich person is black; Yellow stripe to hazel. King kong luster, iron in rutile metallic luster. Half Sex is fragile, hardness 6 ~ 6.5, density 4.2 ~ 4.3 g/cm3, which are rich in iron, nb and ta, high density increases the 5.5 g/cm3 above. Soluble in hot phosphoric acid, cooling diluted sodium peroxide solution can join brown (titanium reaction). Rutile can be produced in gneiss, pegmatite, pomegranate fai (flash) rock mass and placers
Use used to make white, titanium sponge and titanium alloy, artificial rutile, four chlorinated titanium, titanium, fluorine sulfuric acid oxygen titanium potassium, alc13 titanium. Made of titanium dioxide senior white paint, white rubber, synthetic fiber, the coating, the welding wire and reducing agent, rayon light plastic and senior paper packing, and for the telecommunications equipment, metallurgy, printing, printing, dyeing, enamel and other departments. Rutile or the main mineral refining titanium materials. Titanium alloys with high strength and low density, corrosion, high temperature, low temperature resistance, non-toxic, and has the unique properties such as can absorb gas, superconductivity, etc, and special function are widely used in aviation industry, chemical industry, light industry, navigation, medical, defense and sea resources development, etc. According to the report, the world titanium minerals used in the production of more than 90% white paint, and the titanium dioxide products in the paint, rubber, plastics, paper and other industrial application of more and more widely.
