Application
Commercial grade of titanium is used in manufacture of chemical reactors, pumps, holding capacities, pipe arrangements, fittings and other products that opr in aggressive environment (such as chemical mechanical engineering etc.). Titanium is popular in hydrometallurgy of non-ferrous metals. Commercial titanium is intended for covering steel articles. Usage of this metal gives a high engineering-and-economical effect. All these advantages are noticed not only due to increasing of a working life of equipment but also due to an augmentation of process (f.e. in hydrometallurgy of nickel). Possessing a biological safety, titanium is an indispensable material in manufacture of equipment for food industry and for restorative surgery. A strength of this material increases in condition of deep cold. It keeps a perfect plasticity by doing so. This allows using it in cryogenic technique in the capacity of bearing material.
This metal can be easily taken to grit, to colour anodizing, and to other methods of surface finishing. That is why it is also used in manufacture of different art objects. Titanium boride and titanium alloys possess practical importance among all titanium compounds. They are used in energetic nuclear facilities in the capacity of moderators because of high neutron-capture crossing and its refractory quality. Titanium carbide has high hardness. It is used in a composition of instrumental hard alloys that are utilized in a manufacture of cutting tools in the capacity of abraded material. Haloids, silicides, oxides of titanium are used in high-temperature engineering.
