Basic Information on vanadium pentoxide flakes
Alias: Paravandium, Vandic Ammonium, Oxidovanadium Ammonium, etc.
Chemical Properties: Capable of withstanding hydrochloric acid and sulfuric acid, and exhibits superior resistance to corrosion by gases, salts, and water compared to most stainless steels. It does not oxidize in air and can be dissolved in hydrofluoric acid, nitric acid, and aqua regia.
Preparation of vanadium pentoxide flakes Related
Traditional One-Step Process Technology
Process: The wet filter cake containing vanadium or polyvanadate ammonium produced in the initial process is put into a reverberatory furnace. Through prolonged heating, it gradually undergoes drying, deammonization, and melting processes.
Issue Exists
High energy consumption, with an energy utilization rate of less than 30%.
Low recovery rate, currently achievable recovery rates range from 95% to 97%.
Environmental pollution, the ammonia produced in the melting of ferrovanadium is commonly discharged into the air, causing air pollution.
The working environment is poor due to poor sealing, which affects the environment and the health of workers.
New Process of Three-Step Method
Process
Firstly, the vanadium cake is dried into powder by a dryer.
Ammonia is removed by the deammonization equipment.
Melted in a furnace
Advantages
Fast melting speed, high melting strength, and small footprint.
Significantly energy-saving
Recycling rate can reach up to 99%.
The hot air generated by the flash smelting furnace can be used as a drying heat source, effectively utilizing heat and efficiently recycling ammonia vapor in the air, resulting in significant economic benefits.
