Ammonium perrhenate

Description:
Ammonium perrhenate (NH4ReO4) is an inorganic compound characterized by its bright yellow crystalline appearance. It is the ammonium salt of perrhenic acid and is known for its high solubility in water. This compound is primarily used in the preparation of rhenium metal and as a catalyst in various chemical reactions. Ammonium perrhenate is stable under normal conditions but can decompose upon heating, releasing toxic fumes. It is also hygroscopic, meaning it can absorb moisture from the air, which can affect its handling and storage. In terms of safety, it is classified as a potential irritant, and appropriate precautions should be taken when handling it to avoid skin and eye contact. Additionally, due to the presence of rhenium, a rare metal, ammonium perrhenate is of interest in materials science and catalysis research. Overall, its unique properties make it valuable in both industrial applications and academic research.
