**Chemical Formula:** NH₄VO₃
**Ammonium Metavanadate** is a yellow crystalline powder commonly used as a vanadium source in chemical synthesis, catalysis, and ceramic manufacturing. Known for its strong oxidizing properties, it dissolves in hot water and decomposes upon heating, releasing ammonia and forming vanadium pentoxide. This compound plays a key role in metallurgy, dyeing, and analytical chemistry.
**Appearance:**
Yellow to white crystalline powder

**Uses:**
**Pharmaceutical Applications:**
Utilized in biochemical research, particularly in enzyme activity and insulin-mimetic studies involving vanadium compounds.
**Industrial Applications:**
Serves as a precursor in the production of vanadium pentoxide and as a catalyst in sulfuric acid manufacturing. Also used in the creation of vanadium alloys for corrosion-resistant applications.
**Glass & Ceramics:**
Acts as a coloring agent and opacifier in glass and ceramic glazes, imparting vivid green and blue tones.
**Other Applications:**
Used in dyeing and printing fabrics as a mordant and in analytical chemistry for the detection of substances through redox reactions.
