1. Money: On coins, gold and silver and ultrafine niobium nanopowder are sometimes used together as a precious metal in the coins
2. Super alloys: a large portion of niobium to pure metal form or in the form of high-purity niobium and niobium iron-nickel alloy, used in the production of nickel, chromium and iron-base super alloys world. These alloys can be used in jet engines, gas turbine engines, rocket components, turbochargers and heat of combustion equipment;
3. Steel Application: in various micro-alloying elements in steel, niobium waste is the most effective micro-alloying elements, niobium role is so great that the iron atoms are rich in niobium atom, we can achieve performance improvements Steel purposes. Actually Steel added 0.001% -0.1% niobium, is enough to change the mechanical properties of steel;

Put it in a tightly sealed container and store in a cool, dry place.
1. Container: Use airtight containers made of materials that are compatible with metals, such as glass or certain plastics. Avoid using containers that may react with the powder.
2. Environment: Store the container in a cool and dry place to prevent moisture absorption, which may cause oxidation or other reactions.
3. Temperature: Keep the storage area at a stable temperature and avoid extreme heat or cold.
4. Label: Clearly label the container with the contents and any relevant safety information.
5. Safety Precautions: Handle niobium powder with care and use appropriate personal protective equipment (PPE) such as gloves and masks to avoid inhalation or skin contact.
6. Avoid contamination: Make sure the storage area is clean and free of contaminants that could get mixed with the powder.

It is stable at room temperature in the air, and begins to oxidize at 200°C to form a dense oxide film.
Avoid oxides, alkalis, and halogens. Niobium has strong corrosion resistance to acid.

Niobium powder is generally considered to have low toxicity and is not considered hazardous to humans under normal handling conditions. However, like many metal powders, it may pose certain health risks if proper safety precautions are not taken. Here are some precautions:
1. Inhalation: Inhalation of fine metal powders may cause respiratory irritation or other lung problems. Appropriate respiratory protection is recommended when handling large amounts of niobium powder or in dusty environments.
2. Skin Contact: Although niobium does not cause severe skin irritation, it is still a good practice to wear gloves to prevent any potential skin contact.
3. Ingestion: Ingesting metal powders is not safe, so it is important to maintain good hygiene habits to avoid accidental ingestion.
4. Allergic Reactions: Although rare, some people may experience allergic reactions to certain metals, including niobium.
When transporting niobium powder, it is important to follow specific precautions to ensure safety and compliance with regulations. Here are some key considerations to take into account:
1. Packaging: Use appropriate packaging materials that are strong and leak-proof. The container should be sealed and made of materials that do not react with niobium.
2. Label: Clearly label the contents of the package, including the chemical name (niobium powder) and any relevant hazard information. Include handling instructions and emergency contact information.
3. Regulatory Compliance: Check and comply with local, national and international regulations regarding the transportation of metal powders. This may include specific requirements for hazardous materials.
4. Weight Limit: Pay attention to the weight limit of the container to ensure safe loading, unloading and transportation.
5. Avoid contamination: Ensure that the niobium powder is free of contaminants before shipping. Contaminated materials may pose a risk during transportation.
6. Temperature Control: If necessary, consider temperature control measures to prevent any adverse reactions during transportation.
7. Documentation: Prepare all necessary shipping documents, including Safety Data Sheets (SDS) and any required permits or declarations.
8. Handling Precautions: Train personnel involved in the transportation process on proper handling and safety measures for niobium powder.
