1. Physical and chemical properties:

Vanadium pentoxide is an inorganic metal oxide; Gray black flakes; The CAS number is 1314-62-1; The molecular weight is 181.88; The relative density (water=1) is 3.357; Melting point 690 ℃; Boiling point 1750 ℃ (decomposition); Soluble in acid and alkali, slightly soluble in water (pH=3.5-3.6), insoluble in alcohol.

2. Purpose:

Vanadium, also known as the "metal vitamin," is widely used in various fields such as steel, metallurgy, petrochemicals, rubber, porcelain glaze, aerospace, batteries, pigments, glass, optics, paint, electronics, and medicine. Vanadium flakes are mainly used in the steel industry to refine the structure and grain size of steel, increase the grain coarsening temperature, and thereby increase the strength, toughness, and wear resistance of steel; In addition, vanadium flakes have excellent improvement effects in titanium alloys and are used as additives in the aerospace industry.
