Vanadium Pentoxide Flake With Important Characteristics

Flake vanadium pentoxide usually appears as gray-black flakes, but may also exist in the form of orange-yellow, brick-red or reddish-brown crystalline powder. It is slightly soluble in water, insoluble in ethanol, but soluble in strong acids and strong bases. It is an amphoteric oxide, but mainly acidic.

The modern "three-step" vanadium pentoxide tablet production process is to decompose the drying and dehydration, calcination and deammoniation, and melting and casting of the traditional one-step production process into three different process equipment. This process has the advantages of high vanadium yield, good quality, low energy consumption, good environmental protection effect, high degree of automation, safe and stable equipment, etc. The specific steps are as follows: First, the high-temperature flue gas of the melting furnace is used as the drying heat source. After the flue gas is treated by sedimentation and mixed air, it is used as the heat source of the flash dryer to directly dry the wet-based ammonium vanadate. Then, the hot air produced by the combustion of the calcination hot blast furnace is directly calcined in the calcination furnace to remove the ammonia to generate powdered vanadium pentoxide. Finally, the powdered vanadium pentoxide is sent to the discharge port of the melting furnace by a screw conveyor. The vanadium powder is heated and melted in the melting furnace during the falling and accumulation process. The molten vanadium pentoxide liquid enters the water-cooled disc casting machine through the liquid outlet chute to cast the flake vanadium pentoxide.

Flake vanadium pentoxide is the main raw material for smelting ferrovanadium, accounting for more than 80% of the total consumption of vanadium pentoxide. It can be used as an alloy additive to improve the strength, toughness and corrosion resistance of steel. It is used as a catalyst and catalyst in organic chemical industry, accounting for about 10% of the total. At the same time, it is also used in inorganic chemicals, chemical reagents, enamel and magnetic materials, accounting for about 10% of the total.

With the recovery of the global economy and the rapid development of emerging industries, especially the rapid growth of aerospace, new energy vehicles and other industries, the demand for high-quality flake vanadium pentoxide has increased dramatically. This has driven the continued expansion of the flake vanadium pentoxide market and prompted related companies to increase R&D investment to improve product quality and production efficiency. When producing and using flake vanadium pentoxide, attention should be paid to its safety and environmental protection.
