  1. Scandium

  2. Scandium chemical element with the symbol Sc and atomic number 21 in the periodic table of elements, the first element of the first series of transition elements, and has important industrial uses Scandium was discovered in 1879 by Lars Fredrik Nilsson (Sweden). Origin of the name is derived from the Latin word meaning Scandia and Scandinavia. Scandium metallic element mushy bit color silver tends to whiteness. Scandium is burning in the air. Interaction with water produces hydrogen, reacts with the air and with halogens

  3. There scandium metal in Rtviaal (34%) and Aloueckaat., And also found in some raw tin and tungsten. Gets pure scandium as a byproduct when purifying uranium. Scandium is used in some aerospace industries, as well as scandium oxide is used in the manufacture of light bulbs with high intensity. Scandium iodide is used in the manufacture of light bulbs that give light similar to natural sunlight

  4. The main use of scandium, by weight, is in aluminum alloy - scandium for small parts in the aircraft industry. These alloys contain between 0.1% and 0.5% of scandium. They used the Russian fighter jets Scandium oxide or triple-triple scandium oxide is a chemical compound with the formula Sc2O3, and be in the form of a white powder.

  5. Properties Scandium oxide triple undissolved in the water, but dissolved in concentrated acids or hot. Featuring oxide Alsandiom high degree of melting of 2485 Preparation Attend scandium oxide from burning metal scandium oxygen gas at 800 degree

  6. Uses Is used as the raw material for the preparation of other compounds scandium. Used in the electronics industry where it enters in the composition of the data storage devices in the computer industry, which leads to improved performance. Enters in the composition of hydrogen sensors, where it is used as a layer in a thin semiconductor made of gallium nitride, and the electrical conductivity, which varies significantly in the presence of an atmosphere of hydrogen gas
