Purpose (USE)
1. Aluminum fluoride is mainly used in aluminum smelting production to lower the melting point and improve the conductivity of the electrolyte.
2. Aluminum fluoride is used as an inhibitor of secondary fermentation in alcohol production.
3. Aluminum fluoride is used as a flux in ceramic glazes and enamel glazes and as a component of glazes.
4. Aluminum fluoride can also be used as a flux in smelting non-ferrous metals.
STORAGE CONDITIONS
1. Store in a cool, ventilated warehouse.
2. Keep sealed and away from children.
3. It should be stored separately from acids to prevent it from reacting with acidic substances.
4. Store separately from food chemicals and avoid mixed storage.
5. Suitable materials should be available in the storage area to contain spills.
PACKAGE
1. Plastic woven bags, aluminum foil bags, cardboard drums;
2. Other forms of packaging according to customer needs
CHEMICAL PROPERTIES
1. Aluminum fluoride is heated with liquid ammonia or concentrated sulfuric acid, or eutectic with potassium hydroxide.
2. Aluminum fluoride is not reduced by hydrogen, does not decompose but sublimates under strong heat, and is very stable in nature. When heated to 300-400°C, it can be partially decomposed by water vapor into hydrogen fluoride and aluminum oxide.
