Tungsten oxide in the ceramic glaze is used, calcium or magnesium used in the phosphor tungsten. In nuclear physics and nuclear medicine tungsten crystals were used as tungsten bar. Tungsten is used as the X-ray target and in the electronic oven as a heater. Tungsten-containing salt is tungsten carbide inserts‍ permanent in the chemical and leather industries. Bronze tungsten oxide is used in the painting. Because of its low sensitivity to tungsten carbide is used as jewelry, in addition to it's very hard because it is not like other metal polishes are scratches. Some instruments use tungsten-hyun. Appearance of high-purity tungsten gray or dark gray metallic luster, the main ingredient of material for casting; machining cutter and heads, conductor of heat; steelmaking ingredients and additives, advanced molybdenum bar‍  automobile crankshafts, cylinder ingredients and electrodes used to guns, artillery, rockets, satellites, aircraft and ship.
