1. Unique properties of molybdenum
Some uniqueproperties include fine electrical conductivity, excellent thermal conductivity, high stiffness, thermal shock resistance, low thermal expansion coefficient, resistance to molten metal, compatibility with most glass compositions, and strong bonding with glass. All these special features have made molybdenum an attractive metal for developingnew materials. For example, it is machinable by almost every machining process, so it is widely seen as shaped, machined, or fabricated materials.
These properties have opened the door for molybdenum applications to fields of lighting, medical equipment, electronic and electrical devices, thermal spray coating, defense components, aerospace, high temperature furnaces and other related equipments. These applications meantimerequire a combination of molybdenum’unique properties, such as resistance to abrasion, environmental stability vapor pressure, etc.
2. Optical and derived applications
There are applications of molybdenum where one of its properties is particularly dominant and considered. However, many applications require comprehensive materialproperties while cost effectiveness is an inevitablykey factor for commercial purpose. Despite molybdenum’s high price, it is often used only for its ability to offer desiredmaterial propertiestargeting a particular application.
Remember the first molybdenum application was introduced into incandescent lights. Even today, a large quantity of molybdenum metal is consumed by lighting equipments. However, the scenario has changed a lot with the introduction of compact fluorescent lamps (CFL) and light emitting diodes (LED). Still, the use of molybdenum is going to continue glass feedthroughs and support wires in halogen lamps.
Manufacturers of electrical and electronic devices took advantage of lighting experience of molybdenum. They use it for grids and filament supports because of its mechanical solidity and strength in high-temperature conditions. By the year 2009, quantity of molybdenum used in electrical devices has become equal to that used in the lighting application.
3. Weight sensitive applications
Elastic modulus and specific thermal gravity are some explicit properties of molybdenum that has made it a metal of choice for weight sensitive applications such as production of air craft components.
Molybdenum contributes to eliminate lagging technologies such as cathode ray tubes. Thanks to its properties, thin film transistor liquid crystal display, i.e. TFT LCD, was introduced. This technology is the backbone of modern television displays, computers, telecommunications and other instruments.
Finally, we refer briefly tothe use of molybdenum materials in medical field. The molybdenum components are necessary for scanning machines used in computerized axial tomography (CAT). It is also a trace element essential for people’s health. Molybdenum is associated with several diseases and therapies such as anemia, dental caries, immunological reactivity, cellular redox homeostasis, Wilson’s disease, diabetes, cancer, Huntington’s disease, atherosclerosis, neural tube defects, and so on.
