Ammonium metatungstate (AMT) is a white crystalline powder that is used in the production of tungsten metal, tungsten carbide, and other tungsten compounds. It is a stable compound under normal conditions, but it can decompose at high temperatures or in contact with strong acids or oxidizing agents.
Here are some guidelines for the safe storage and handling of ammonium metatungstate:
Storage: AMT should be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, oxidizing agents, and combustible materials. The storage area should be clearly labeled and access should be restricted to authorized personnel only.
Handling: When handling AMT, wear appropriate personal protective equipment such as gloves, goggles, and a lab coat. Avoid direct contact with skin, eyes, and clothing. AMT should be handled in a fume hood to prevent inhalation of the powder. Use a dust mask or respirator if necessary.
Transportation: AMT should be transported in a sealed, unbreakable container to prevent accidental spills or leaks. The container should be labeled with the name of the chemical, the hazard warnings, and the name of the supplier.
Disposal: AMT should be disposed of according to local, state, and federal regulations. It should not be disposed of in regular trash or poured down the drain. Contact your local hazardous waste disposal facility for instructions on proper disposal.
In summary, ammonium metatungstate should be stored in a cool, dry, well-ventilated area away from incompatible materials, handled with appropriate personal protective equipment, transported in a sealed, unbreakable container, and disposed of according to local regulations.
