Properties Uses and Facts about Molybdenum
What is Molybdenum
Molybdenum is a metal, classified as a transition metal, and chemically
molybdenum is an element. Molybdenum has a density of 10.2 grams per cubic
centimeter, an atomic mass of 95.95 AMU, an atomic number of 42, and a
symbol (Mo). Molybdenum is located in Group 6, Period 5 and Block (D) in the
Periodic Table. Its atom has 42 electrons, 42 protons, 54 neutrons and 5
energy levels. Molybdenum metal is found in the solid state at room
temperature, with a melting point (melting point) of 2610 °C (4730 °F) and a
boiling point (boiling point) of 4639 °C (8382 °F).
Molybdenum metal was discovered by the Swedish chemist Carl Wilhelm Scheele
in 1778.
Properties of Molybdenum Metal
- Molybdenum is a silvery-white lustrous metal.
- Molybdenum has very good corrosion resistance.
- Molybdenum is a soft metal, and cannot be hardened by heat treatment.
- Molybdenum does not react with oxygen at normal temperature, it reacts with oxygen only at high temperature.
- Molybdenum reacts slowly with acids.
- Molybdenum does not dissolve in most acids, while it dissolves in hot sulfuric acid and nitric acid.
- Molybdenum does not react with water at room temperature, whereas at temperatures above 600 °C it reacts with water to form molybdenum trioxide.
- As the thickness or diameter of the structure made of molybdenum decreases, its tensile strength increases. This property of molybdenum makes it extremely useful for making wire.
- Molybdenum is a good conductor of electricity and heat.
Uses of Molybdenum Metal
- Molybdenum is most commonly used in making alloys.
- Molybdenum is used to increase the ductility, strength and corrosion resistance of steel.
- Molybdenum maintains the strength of steel at higher temperatures.
- Molybdenum disulfide (MoS2) is used as a lubricant operating at high temperatures.
- Alloys made of molybdenum and nickel are heat and corrosion resistant, these alloys are used in the chemical industry.
- Molybdenum is used as a catalyst in the petroleum industry, the polymer industry, and the plastics industry.
- Molybdenum is used to make aircraft and missile parts.
- Molybdenum is used in the manufacture of special equipment that is used under high temperatures and harsh conditions, such as rifle barrels, propeller shafts, spark plugs, electrical equipment used at high temperatures, nuclear plants, boiler plates, etc. .
Interesting Fzcts about Molybdenum metal
- Molybdenum is the element with the sixth highest melting point.
- Molybdenum is an essential nutrient for plants.
- Molybdenum is present in more than 50 enzymes found in the bodies of plants and animals.
- Molybdenum is slightly different than other soil nutrients in that it is more soluble in alkaline soil than in acidic soil.
- There are 35 different isotopes of molybdenum, seven of them are naturally occurring, the isotope of molybdenum Mb-98 is found in the most quantity, which is about 25% of the total molybdenum.
- Molybdenum steel was used in the famous German howitzer Big-Bertha, as ordinary steel would melt under the heat of the cannon.
- Molybdenum is mainly obtained as a by-product during the mining of copper and tungsten.
