Vanadium Pentoxide Falek is an important inorganic compound.
vanadium pentoxide flake physical properties
Appearance and Properties: Orange-yellow, brick-red or red-brown crystalline powder, can also be presented as gray-black flakes.
Melting point: about 690 ℃ (there are also information mentioned about 670 ℃ melting)
Boiling point: 1750°C (decomposition)
Solubility: slightly soluble in water (mass concentration of about 0.07g / L), the solution is yellow; insoluble in ethanol, but soluble in strong acids and strong bases.
vanadium pentoxide flake chemical properties
Amphoteric oxide: vanadium pentoxide is amphoteric oxide, but acidic is dominant.
Decomposition properties: It volatilizes significantly at 700~1125℃ and decomposes into oxygen and vanadium tetraoxide. This property makes it a catalyst for many organic and inorganic reactions.
Oxidizing property: It is a strong oxidizing agent, easily reduced to various low value oxides.
vanadium pentoxide flake uses
Metallurgical industry: vanadium pentoxide is widely used in metallurgical industry, mainly used for smelting ferrovanadium, and as an alloy additive, accounting for more than 80% of the total consumption of vanadium pentoxide.
Chemical industry: It is used as catalyst (catalyst) of organic chemical industry, accounting for about 10% of the total amount. In addition, it is also used as inorganic chemicals, chemical reagents, enameling and magnetic materials, etc., accounting for about 10% of the total amount (also mentioned as 15% in some sources).
In summary, flake vanadium pentoxide is an inorganic compound with wide application value, playing an important role in metallurgy, chemical industry and other fields. However, due to its toxicity, it is necessary to strictly observe the safety operation procedures in the process of use to ensure the safety of personnel and the environment.
