Vanadium is a hugely versatile element and the addition of small amounts of vanadium to steel offers the ability to enhance the metal making it stronger, tougher and lighter. Due to its versatility, its usage has risen significantly in recent years as the number of innovation-driven industries depending on vanadium for their operations and products continues to increase.
What is Molybdenum Dioxide?
Molybdenum dioxide is the chemical compound with the formula MoO2. It is a violet-coloured solid and is a metallic conductor. It crystallizes in a monoclinic cell, and has a distorted rutile, (TiO2) crystal structure. In TiO2 the oxide anions are close-packed and titanium atoms occupy half of the octahedral interstices (holes). In MoO2 the octahedra are distorted, the Mo atoms are off-centre, leading to alternating short and long Mo – Mo distances and Mo-Mo bonding. The short Mo – Mo distance is 251 pm which is less than the Mo – Mo distance in the metal, 272.5 pm. The bond length is shorter than would be expected for a single bond. The bonding is complex and involves a delocalisation of some of the Mo electrons in a conductance band accounting for the metallic conductivity.
MoO2 can be prepared :
- by reduction of MoO3 with Mo over the course of 70 hours at 800 °C. The tungsten analogue, WO2, is prepared similarly.
- 2 MoO3 + Mo → 3 MoO2
- by reducing MoO3 with H2 or NH3 below 470 °C
Single crystals are obtained by chemical transport using iodine. Iodine reversibly converts MoO2 into the volatile species MoO2I2.
Molybdenum oxide is a constituent of “technical molybdenum oxide” produced during the industrial processing of MoS2:
- 2 MoS2 + 7O2 → 2MoO3 + 4SO2
- MoS2 + 6MoO3 → 7MoO2 + 2SO2
- 2 MoO2 + O2 → 2MoO3
MoO2 has been reported as catalysing the dehydrogenation of alcohols, the reformation of hydrocarbons and biodiesel. Molybdenum nano-wires have been produced by reducing MoO2 deposited on graphite. Molybdenum oxide has also been suggested as possible anode material for Li-ion batteries.
Uses of Molybdenum Trioxide
Molybdenum trioxide is used to manufacture molybdenum metal, which serves as an additive to steel and corrosion-resistant alloys. The relevant conversion entails treatment of MoO3 with hydrogen at elevated temperatures:
- MoO3 + 3 H2 → Mo + 3 H2O
It is also a component of the co-catalyst used in the industrial production of acrylonitrile by the oxidation of propene and ammonia.
Because of its layered structure and the ease of the Mo(VI)/Mo(V) coupling, MoO3 is of interest in electrochemical devices and displays. Molybdenum trioxide has also been suggested as a potential anti-microbial agent, e.g., in polymers. In contact with water, it forms H+ ions that can kill bacteria effectively.
The following are some of our available Molybdenum (Mo) chemicals:
- Ammonium Dimolybdate
- Ammonium Heptamolybdate
- Molybdenum Trioxide
- Molybdic Acid
- Sodium Molybdate
Because Vanadium strengthened steel is lightweight and offers increased durability, it is ideal for use in infrastructure and transportation systems.

Who Are We?
London Chemicals & Resources Ltd (LCR) operates globally, processing non-ferrous metal-containing secondaries and distributing a range of metal salts and alloys which, in many cases, are recycled from these secondaries.
We hold exclusive agencies from Full Yield Industry Co Limited based in Taiwan and AGR-CR based in Spain. LCR source more than 90% of the spent catalysts and other feedstocks processed at Full Yield and represent them exclusively for sales of vanadium, molybdenum and nickel chemicals.
We also represent a completely new processing plant; AGR-CR treating spent catalysts and other secondaries and scheduled to start commercial operations in Q1, 2020. LCR offers commercially competitive recycling options with an emphasis on environmentally sound management. Our experienced, friendly and knowledgeable staff are familiar with relevant legislation, transport procedures and documentation including trans-frontier notifications; REACH, SDSs and ADR. Quality, consistency and reliability are all important watchwords for LCR ensuring that our customers return again and again.
We are regularly purchasing and recycling secondaries containing cobalt, copper, molybdenum, nickel, tungsten, vanadium and zinc found typically in boiler ashes and slags, catalysts spent – unused or out of date, drosses, dusts, filter cakes, furnace dust, galvanic solution residues, grindings and grinding sludges, metallics, shavings, metal powders, picking solutions, plating sludges, production wastes, residues, skimmings, sludges, wastewater treatment residues.
