Typical Chemical Analysis
Tungsten micropowder is a lustrous and silvery-white metal. It has the highest melting point than any other metal. Mainly tungsten is employed in filaments in incandescent light bulbs; it is also utilized in electric contacts and arc-welding electrodes. Moreover, Tungsten is applied in alloys, for instance, steel, to which it imparts great strength. Cement carbide is the most indispensable use for tungsten: its main component is tungsten carbide (WC).
Tungsten exhibits the strength to our cast iron and it manufactures remarkable cutting tools for the machining of steel. X-ray tubes for medical utilize have a tungsten emitter coil and the screen employed to view X-rays rely on calcium and magnesium tungstate phosphors to convert X-rays into blue visible light. Tungsten Micropowder has also utilized in microchip technology and liquid crystals displays.
Pure Tungsten micropowder is a light gray and whitish metal. It is also is soft enough. It can be easily cut with a hacksaw and ductile enough to be drawn into wire or extruded into various shapes. If doped with other materials, tungsten becomes brittle and hard to work with. It is used to make filaments for fluorescent light bulbs and television tubes. Tungsten forms compound with magnesium and calcium that have phosphorescent properties.
Tungsten micropowder inflates at nearly the same rate as borosilicate glass. In addition, it is used to make metal to glass seals and it is also employed as a target for X-ray production, as heating elements in electric furnaces and for parts of spacecraft and missiles which must withstand high temperatures. At high temperatures, Tungsten is alloyed with steel to produce tough metals that are stable.
Tungsten-steel alloys are utilized to make such things as high-speed cutting tools and rocket engine nozzles. Tungsten carbide (WC) is an extraordinary hard tungsten compound. It is utilized in the tips of drill bits, high-speed cutting tools, and mining machinery. Tungsten disulfide (WS2) is a dry lubricant and it can be utilized to temperatures as high as 500°C.
